海外TECH	DEV Community	Front End Development : Easy or Hard	https://dev.to/jagroop2000/front-end-development-easy-or-hard-1cpo	Front End Development Easy or HardMost of the people thought Front End Development is easy and anyone can learn within few days or it s Just HTML CSS etc But Actually it s not YES IT S NOT It s as difficult as learning Back End Development or any other Top Notch Technologoies So here are some more specific challenges that front end developers may face Cross browser compatibility Different web browsers can interpret and display HTML CSS and JavaScript in different ways so front end developers must ensure that their code works consistently across all major browsers Performance optimization Front end developers must be mindful of how their code impacts the performance of a website particularly on mobile devices with limited processing power and slower internet connections This may involve optimizing images minimizing the use of resource intensive features and using performance enhancing techniques such as lazy loading Responsive design With the increasing number of devices and screen sizes that people use to access the web it s important for websites to be responsive meaning they should look and function well on any device This requires front end developers to have a strong understanding of how to build layouts that adapt to different screen sizes and resolutions Testing and debugging YES testing and Debugging is also cosider as part of Front End Development Front end developers must be able to test their code to ensure that it is working correctly and they must be able to troubleshoot and fix any issues that may arise This can be a time consuming and challenging process especially when dealing with complex or poorly written code Keeping up with new technologies The field of front end development is constantly evolving with new frameworks libraries and tools being introduced all the time Front end developers must stay up to date with these developments in order to remain competitive in their careers Collaborating with other team members Front end development is often a collaborative process and front end developers may need to work with designers back end developers project managers and other stakeholders to build and maintain websites and web applications Effective communication and collaboration skills are therefore important for front end developers to possess So finally I would say that It s not Easy Learning any skill even it is front end back end blockchain cloud computing AI ML etc is not easy each of the skill require time need hardwork and lot s and lot s of practice	2023-01-03 08:56:14

protection	https://dev.to/akimyou/goodbye-to-passwords-with-webauthn-the-future-of-online-identity-protection-31jl	Goodbye to passwords with WebAuthn the future of online identity protection Goodbye to passwords with WebAuthn the future of online identity protection The shortcomings of traditional authentication methods As the internet becomes more prevalent we rely more and more on online services to complete our daily work and entertainment However online identity authentication has always been a thorny problem and traditional authentication methods such as passwords SMS email verification codes OTPs one time passwords or two factor authentication all have some drawbacks Passwords Using passwords for authentication is the most common method but passwords can be prone to brute force attacks leaks or being forgotten making them not secure or convenient SMS email verification codes When using SMS email verification codes for authentication a code is sent to the user s phone and the user must enter it on the website or app to log in However SMS verification codes can be intercepted or deceived leading to authentication failure OTP one time password OTP is a method of authentication using a single use password OTPs typically generate a dynamic password that is changed every so often and the user must enter it on the website or app to log in OTP allows for authentication when the device is not nearby but if the OTP is intercepted or deceived it can also lead to authentication failure Two factor authentication Also known as two factor authentication this is a method of authentication that requires a user to provide two different types of credentials in order to pass authentication Typically two factor authentication requires something the user knows such as a password and something the user has such as a phone While two factor authentication is more secure than a single factor such as a password it can still be inconvenient and vulnerable to interception or deception What is WebAuthn Is there a way to authenticate identity that is both secure and doesn t compromise user experience That s where WebAuthn comes in WebAuthn is a new browser based online identity authentication technology developed by the World Wide Web Consortium WC that allows users to authenticate themselves using hardware based identity verification devices such as Apple TouchID and Windows Hello or biometric sensors on mobile devices WebAuthn aims to provide users with a more secure and convenient way to authenticate online identity and is supported by most modern web browsers Here s how WebAuthn works The user registers their identity during their first login The user s device generates a private key The user s device signs the login information with the private key The server verifies the signature and confirms the user s identity During this process a password is not used Instead WebAuthn uses digital signature technology to verify the user s identity which uses public key encryption algorithms to provide even greater security What problems does WebAuthn solve for identity verification WebAuthn has many advantages over traditional password authentication methods First it provides higher security Because it doesn t use passwords it doesn t pose a security threat to accounts due to password leaks In addition WebAuthn can use multiple verification methods including fingerprint recognition and facial recognition which are very difficult to impersonate thereby greatly improving account security Second WebAuthn provides a more convenient login experience Users only need to register their identity during their first login after which they can use WebAuthn for quick login Users don t have to remember passwords and don t have to worry about the hassle of forgetting passwords Of course WebAuthn also has some drawbacks For example it can only be used on devices that support WebAuthn so it may not be suitable for older devices In addition to create a public private key pair for a website or app the user must first register on the website or app and for users unfamiliar with WebAuthn it may take some time to learn and understand this method of identity verification Overall WebAuthn s appearance today with passwords under frequent attack provides us with higher security and a more convenient login experience What does web authn completed app do web authn completed app is a demo of a WebAuthn based authentication process that aims to help interested developers better understand and develop WebAuthn more quickly The project is built with Vue Typescript Vite for the client Express for the server and MySQL for the database The project also includes detailed instructions on how to operate and start the app in different scenarios to make it easier for developers to deploy and further develop The demo can be accessed online at Source code is available on githubThe demo has been demonstrated on WIN and Android devices but compatibility with devices and browsers is also a consideration To use the demo you will need one of the following devices An Android device with a biometric sensorAn iPhone or iPad with iOS or later and Touch ID or Face IDA MacBook Pro or Air with macOS Big Sur or later and Touch IDA Windows H or later device with Windows HelloYou will also need one of the following compatible browsers Google Chrome or laterMicrosoft Edge or laterSafari or laterNote all user data registered through will not be used and is only for demo user statistics If you have any concerns you
