海外TECH	Engadget	The best password managers for 2024	https://www.engadget.com/best-password-manager-134639599.html?src=rss	We use passwords for everything From our bank accounts to free social media sites our password footprints spread all over our digital landscape But that means if you re reusing the same ones over and over again you re opening yourself up to hackers potentially finding one in a leak and getting into your most sensitive accounts That s where password managers come in They store all your credentials in one place taking the burden off of you to remember them all and even offer stronger password options to help prevent reuse in the future Yet it s a confusing space filled with extra features and security gaps that can make it hard to navigate We tested out nine of the best password managers available now to help you choose the right one for your needs Password remains our top pick thanks to its zero knowledge policy numerous security features and general ease of use but there are other solid password managers out there to consider as well How do password managers work Think of password managers like virtual safe deposit boxes They hold your valuables in this case usually online credentials in a section of the vault only accessible to you by security key or a master password Most of these services have autofill features that make it convenient to log in to any site without needing to remember every password you have and they keep your credit card information close for impulse purchases But given that passwords are one of the top ways to keep your online identity secure the real value of password managers is staying safe online It s just not possible without a password manager to have unique long and hard to guess passwords Florian Schaub an associate professor of information and of electrical engineering and computer science at the University of Michigan said Common guidance states that secure passwords should be unique with the longest number of characters allowed and uppercase letters lowercase letters numbers and special characters This is the exact opposite of using one password everywhere with minor variations depending on a site s requirements Think of how many online accounts and sites you have credentials for ーit s an impossible task to remember it all without somewhere to store passwords safely no a sticky note on your desk won t cut it Password managers are more readily accessible and offer the benefit of filling in those long passwords for you Are password managers safe It seems counterintuitive to store all your sensitive information in one place One hack could mean you lose it all to an attacker and struggle for months or even years to rebuild your online presence not to mention you may have to cancel credit cards and other accounts But most experts in the field agree that password managers are a generally secure and safe way to keep track of your personal data and the benefits of strong complex passwords outweigh the possible risks The mechanics of keeping those passwords safe differs slightly from provider to provider Generally you have a lengthy complex master password that safeguards the rest of your information In some cases you might also get a security key to enter when you log in to new devices This is a random string of letters numbers and symbols that the company will send you at sign up Only you know this key and because it s stored locally on your device or printed out on paper it s harder for hackers to find These multiple layers of security make it difficult for an attacker to get into your vault even if your password manager provider experiences a breach But the company should also follow a few security basics A zero knowledge policy means that the company keeps none of your data on file so in the event of an attack there s nothing for hackers to find Regular health reports like pentests and security audits are essential for keeping companies up to par on best practices and other efforts like bug bounty programs or hosting on an open source website encourage constant vigilance for security flaws Most password managers now also offer some level of encryption falling under the Advanced Encryption Standard AES AES bit is the strongest because there are the most number of possible combinations but AES bit or bit are still good Who are password managers for Given their universal benefit pretty much everyone could use a password manager They re not just for the tech savvy people or businesses anymore because so much sensitive information ends up online behind passwords from our bank accounts to our Netflix watch history That s the other perk of password managers safe password sharing Families friends or roommates can use them to safely access joint accounts Texting a password to someone isn t secure and you can help your family break the habit by starting to use one yourself Lisa Plaggemier executive director at National Cyber Security Alliance said Streaming is the obvious use case but consider the shared bills file storage and other sites you share access with the people around you as well Are password managers worth it You likely already use a password manager even if you wouldn t think to call it that Most phones and web browsers include a log of saved credentials on the device like the passwords keychain in the settings of an iPhone That means you ve probably seen the benefits of not having to memorize a large number of passwords or even type them out already While that s a great way in the downfall of these built in options are that they tend to be device specific If you rely on an Apple password manager for example that works if you re totally in the Apple ecosystem ーbut you become limited once you get an Android tablet Lujo Bauer professor of electrical and computer engineering and of computer science at Carnegie Mellon University said If you use different devices for work and personal use and want a secure option for sharing passwords with others or just don t want to be tied to one brand forever a third party password manager is usually worth it How we testedWe tested password managers by downloading the apps for each of the nine contenders on iPhone Android Safari Chrome and Firefox That helped us better understand what platforms each manager was available on and see how support differs across operating systems and browsers As we got set up with each we took note of ease of use and how they iterated on the basic features of autofill and password generators Nearly all password managers have these features but some place limits on how much you can store while others give more control over creating easy to type yet complex passwords From there we looked at extra features like data breach monitoring to understand which managers offered the most for your money Finally we reviewed publicly available information about security specs for each This includes LastPass which more experts are shying away from recommending after the recent breach For the sake of this review we ve decided not to recommend LastPass at this time as fallout from the breach still comes to light The company disclosed a second incident earlier this year where an unauthorized attack accessed the company s cloud storage including sensitive data Since then hackers have stolen more than million in cryptocurrency using private keys and other information stored in LastPass vaults These are the password managers we tested PasswordLastPassBitwardenDashlaneKeeperNordPassEnpassNorton password managerLogMeOnceOther password managers we testedLastPassFor a while security experts considered LastPass a solid choice for a password manager It s easy to use has a slew of helpful extra features and its free version gives you a lot But we decided not to include LastPass in our top picks because of the high profile data breaches it has experienced over the past couple of years KeeperKeeper met a lot of the basic criteria we tested for like autofill options and cross platform availability We liked its family plan options too that can keep your whole household secure But we didn t think its extra features like the encrypted messaging app added much value Plus it has a self destruct feature after five incorrect login attempts which despite adding extra protection could be a recipe for disaster for casual users EnpassEnpass works well as an affordable password manager That includes an inflation beating lifetime access pass instead of a monthly payment for users really committed to the service Still it was confusing to set up across devices and because Enpass stores data locally as opposed to in the cloud we struggled to get started with it on mobile NortonA familiar name in security we were excited to test out Norton s password manager While it s free its features seem underdeveloped It lacked password sharing account recovery and complex form filing tools that come standard in many of the other password managers we tested LogMeOnceLogMeOnce comes with a wide range of premium tiers from professional to family that include different levels of storage and features But when we tested it lacked some basic cross platform availability that other password managers had already like compatibility with Mac and Safari FAQsWhy use a password manager Using a password manager can enhance your online security They store all of your complex passwords and autofill them as needed so that you can have unique strong passwords across the web without remembering each of them yourself In many cases unique passwords are your first defense against attack and a reliable manager makes it easier to keep track of them all Are password managers percent safe Password managers are a secure way to store your credentials Experts in the field generally agree that the benefits of accessibility when storing complex passwords outweigh the possibility of attack like what happened with LastPass But with any service it can vary from provider to provider You should look out for zero knowledge policies regular security audits pentests bug bounty programs and encryption when choosing the right secure password manager for you What if I forget my master password Forgetting a master password won t necessarily lock you out for good but the recovery process varies from provider to provider Some services give you a security key at sign up to enter when you log into new devices It can also be used to securely recover your account because it s a random string of keys stored locally that only you have access to Other services however have no way to recover your vault So creating a master password that you won t forget is important How can I make a good master password A good master password should be unique with the longest number of characters allowed and uppercase letters lowercase letters numbers and special characters Experts often recommended thinking of it like a passphrase instead of a password to make it easier to remember For example you can take a sentence like My name is Bob Smith and change it to Myn misBbm th to turn it into a secure master password that you won t forget This article originally appeared on Engadget at	2024-02-19 13:01:26
海外TECH	Engadget	Sony A9 III review: The future of cameras is fast	https://www.engadget.com/sony-a9-iii-review-the-future-of-cameras-is-fast-130057924.html?src=rss	After letting rival camera companies catch up for the last few years Sony laid down a gauntlet with the megapixel A III It s the world s first mirrorless camera with a global shutter a much awaited holy grail feature It completely eliminates rolling shutter distortion found on CMOS cameras by reading the entire sensor at once It also boosts speed and removes the need for a mechanical shutter As a pioneering product it s not cheap at but you can expect the technology to come down in price in the future And there is a downside Image quality is reduced compared to regular cameras due to the nature of a global shutter Is it worth trading off image quality for extra speed and lack of distortion especially compared to stacked sensor cameras that are already pretty quick To find out me and my pro photographer friends put a final production model through a variety of shooting scenarios Body and handlingThe A III is Sony s best handling camera yet borrowing all the latest features of recent models like the AR V It s very light for a full frame camera at just grams And the redesigned grip is more comfortable and secure which is a big help to working pros especially with heavy lenses By comparison Sony s A can be hard on one s hands over a full day according to my photographer pals There are three top control dials making it easy to find primary settings in fully manual mode It has a pair of dual dials with one for video photos and S amp Q plus shooting modes and the other controlling burst along with autofocus You also get a rear joystick control dial and no less than custom buttons With everything well placed it s a cinch to shoot manually When you do need to delve into the menus those are also well laid out Settings are divided logically into categories while the home menu shows key options shutter speed white balance etc at a glance Everything can be customized and you can back up your settings to a memory card The high resolution two million dot rear display is of course touch sensitive for focus and menu control It flips out and tilts up or down to please both photographers and creators The viewfinder is the best on any camera with million dots at Hz or half that at Hz That level of sharpness makes it easy to check focus and colors Again this is Sony flexing its tech muscles as the primary camera EVF supplier Battery life is a solid shots but you can double that with a new vertical grip which also gives you a better hold of the camera It has a dual card slot setup with both SD UHS II and CFexpress As usual with Sony the latter is the slower Type A variety though Those are less than half the speed of CFexpress type A but their smaller size allows Sony to do the dual slot setup Other key features include headphone and mic ports with the option to add Sony brand microphones or audio accessories to the hotshoe There s also a full sized HDMI port USB C charging port ethernet live streaming capability and more PerformanceWith the global shutter dual Bionz processors and the same dedicated AI processor found on the AR V Sony s A III is the fastest full frame camera in the world Compressed RAW bursts can be shot at an incredible fps with autofocus and auto exposure or you can dial that down to fps or fps Steve Dent for EngadgetA big caveat is that the fps mode only works with supported Sony lenses while third party lenses are all limited to fps Hopefully the company will address that in a future firmware update The buffer holds RAW frames so it fills up in less than two seconds at maximum speed It takes longer to clear the buffer than it should due to the CFexpress Type A cards If you use SD UHS II cards instead it takes about twice as long to clear In any case shooting at fps is major overkill most of the time unless you like wading through thousands of photos later on Sony does have a solution though You can shoot at say a still very fast fps then press the C button to enable the top speed at key moments That way you ll get the shot you want without wasting frames The A III is also the first Sony camera to use a pre capture mode that saves a second of photos when you half press the shutter button After you fully press it those photos are saved along with any taken after img alt Sony A III review The future of cameras is fast src style height px width px Nathanael CharpentierYour photos will usually be sharp too The phase detect focus points allow for extremely rapid and accurate autofocus in most situations For regular continuous AF it can keep up with even the fastest action The AI powered subject detection shines too Face tracking works with subjects farther away and it follows someone tenaciously even when they duck behind obstacles Human tracking is fast and fluid and you can easily see if it s locked onto eyes face or body It can detect birds animals or both along with insects cars and trains You can also select any distinctive object and the system will usually track it reliably The bottom line is that it rarely misses focus so it s great for professional sports wildlife weddings and more Of course it s not infallible and can mix up subjects but is better than any camera I ve tried to date img alt Sony A III review The future of cameras is fast src style height px width px Nathanael CharpentierThe A III has no need for a mechanical shutter because there s no rolling shutter distortion meaning you can shoot in complete silence at all times With that it s perfect for sports like golf as you can shoot a player in mid swing without disturbing them and a club in motion won t be distorted It also allows for extremely fast shutter speeds up to th and it can sync with supported flashes all the way up to that speed It also eliminates the flicker and banding from venue lights another big aid for sports photographers Sony has also improved its in body stabilization significantly boosting it to stops with supported lenses That allows shots down to a quarter second or less matching Canon s EOS R and besting the Nikon Z and Sony s own A Image qualityAs mentioned the primary issue with this camera is image quality So is how much does it fall below regular CMOS cameras To test that I shot in situations including gymnasiums night scenes bird shooting an airport and more There s no question that dynamic range is reduced compared to Sony cameras like the A at least by a stop The reason is that the sensor has less light capacity due to the space taken up by the extra electronics It also has a smaller ISO range both on the high and low end Minimum ISO is not great at and at the high end ISO is limited to half that of the A II In general there s more noise and less dynamic range at any given ISO setting than the A II At the same time the resolution is lower than rivals like the Nikon Z and Sony s own AR V and A So for landscapes portraits and other types of photography where dynamic range and resolution is important and speed isn t the A III isn t the best choice img alt Sony A III review The future of cameras is fast class eehero url src style height px width px That said you d need to pixel peep to notice any major difference in image quality between rival megapixel cameras up to about ISO For the intended audience of sports action and wildlife shooters it s more than sufficient Beyond that images are noisier but still usable up to the maximum ISO with noise reduction Sony appears to have more aggressive noise reduction for JPEG images at higher ISOs I had no difficulty extracting good shots in dark scenes at ISO or even ISO And as mentioned you have more control with a flash than any other camera on the market so that s a solid option in low light Otherwise images are typical for Sony with accurate colors and skin tones The bit RAW files are easy to work with and allow some pushing and pulling particularly in highlights VideoSteve Dent for EngadgetSony took advantage of the global shutter to make the A III its most capable mirrorless camera for video K at up to fps is supersampled using the full K sensor width while K at fps can also be shot using the full sensor albeit with pixel binning That mode supports full fps playback as well or slower playback modes via the slow and quick S amp Q setting RAW K capture at fps is also possible using an external recorder All of those modes are available with bit S Log recording to expand dynamic range in challenging lighting conditions That s just the start of the A III s video powers Autofocus is as fast and accurate in video as stills mode and has all the same AI features That means you ll be sure to keep even fast moving subjects sharp whether they re people birds animals or vehicles Those who prefer to shoot manually can employ Sony s handy focus map feature It has the auto framing seen on previous Sony models like the ZV E that lets YouTubers move around while filming themselves You also get the digital zoom feature that reduces focus breathing for supported lenses with some loss of quality img alt Sony A III review The future of cameras is fast src style height px width px Steve DentAirplane propeller distortion in video is a telltale sign of a rolling shutter camera so naturally we had to test the A III at an airport against Sony s stacked sensor A Our findings While the A still produces bendy propellers they re of course dead straight on the A III That trivial test has large implications You can shoot things like whip pans or a fast moving train that you d never try with a rolling shutter sensor And since everything is exposed at once like a film camera it s more cinematic The A III does have some video competition as RED just launched a pair of full frame global shutter cinema cameras last month It has the same excellent video stabilization capabilities as the ZV E Regular optical stabilization is good for handheld shots without much movement or you can kick in the dynamic active mode for walking That provides near gimbal levels of smoothness though there s a considerable zoom and loss of sharpness Much as with photos video quality isn t quite up to other full frame cameras with more noise in general I shot in S Log most of the time to maximize dynamic range and was satisfied with the results In low light I was forced to use some noise reduction Quality is still better than any APS C mirrorless or cinema camera I think the global shutter advantages particularly the elimination of rolling shutter will be worth the tradeoff in quality for a large number of videographers Wrap upSteve Dent for EngadgetSony launched its first full frame mirrorless camera the A years before rivals and was first to market with backside illuminated and stacked sensors Lately though rivals especially Canon have been catching up and the field has leveled With the first global shutter camera Sony has taken a leap ahead once again Image quality has held global sensor cameras back but Sony clearly felt that the time was finally right It was a wise calculation ーthe A III is far better than I expected for a first gen product It offers mind blowing speeds and incredible video capabilities with a relatively small cost in image quality Its primary rivals are the Canon R Sony s own A the Nikon Z and Z all stacked sensor cameras The latter three offer much higher resolution and better picture quality plus shooting speeds that are still darn fast They all have some rolling shutter though along with flicker and flash sync issues that don t exist on the A III Whether it s worth risking that kind of money on new and unproven stacked sensor tech depends on the buyer Action photographers and videographers won t blink at the cost if they advantages of global shutter will help them make money Unless you really need those benefits though Nikon s Z and Z along with Sony s A are more versatile cameras ーand the Z is significantly cheaper This article originally appeared on Engadget at	2024-02-19 13:00:57
