How does persistent authentication work in jwt authentication?


Asked by Dior McLean on Nov 29, 2021 FAQ



Persistent authentication session variables allow claims-based authorization with JWT Authentication Scheme. With claims-based authorization, authorizes a user, based on the claim value present in the token and supports storing the claims using the session variables configured.
Besides,
If JWTs are used for Authentication, they will contain at least a user ID and an expiration timestamp. If you would like to know all the details about the JWT format in-depth including how the most common signature types work, have a look at this post JWT: The Complete Guide to JSON Web Tokens.
Also Know, JSON Web Token (JWT) is an open standard (RFC 7519) for securely transmitting information between parties as JSON object. It is compact, readable and digitally signed using a private key/ or a public key pair by the Identity Provider (IdP). So the integrity and authenticity of the token can be verified by other parties involved.
Keeping this in consideration,
The server checks JWT token to see if it's valid or not. After the token is validated, the server sends a status message to the client. User Login - User normally logs in with his/her credentials such as User Name and Password.
Accordingly,
User’s Client uses the JWT to access protected resources by passing the JWT in HTTP Authorization header. Resource server then verifies the authenticity of the token using the secret salt/ public key. Just like any other authentication mechanism, JWT also has its own pros and cons.
