🔐How User Authentication Work?

Authentication of user accounts for web and app access. Identity is required for web access to your apps and data: only you should be able to see your stuff!

Apps use “Authentication” to verify that you are who you say you are: it can be as simple as a password or as complex as biometrics (e.g. fingerprint or facial recognition).

The most common method of authentication is username and password, but schemes such as single-sign-on, OAuth, SMS Pin and Password-less Authentication with Magic Links and SMS OTP code are becoming more popular.

📟 SMS OTPs are also used for Two-factor authentication (2FA) security system that requires two or more pieces of evidence.

Authentication on the backend can be accomplished through the use of cookies, session tokens, JSON Web Tokens (JWTs), and/or other complicated cryptography combinations.
