How do you handle JWT expiration and revocation in your web api?

2 How do JWTs and OAuth 2.0 work together?

JWTs and OAuth 2.0 work together to provide a secure and scalable solution for web API authentication and authorization. The process begins when the client requests an access token from the authorization server, providing its credentials and the scope of access it needs. The authorization server validates the client and asks the user to consent to the requested scope of access. If the user grants or denies the consent, the authorization server redirects the client to a callback URL with an authorization code. This code is exchanged for an access token, which is a JWT that contains the user's identity, the scope of access, and other claims. The client sends this token as a bearer token in the authorization header of each web API request, which is then verified by the resource server by checking its signature, expiration, and scope. Access is either granted or denied based on these criteria.

3 How do you handle JWT expiration and revocation in your web API?

One of the challenges of using JWTs for web API security is handling token expiration and revocation. Token expiration is setting a time limit for validity, while token revocation is invalidating a token before its expiration, such as in the case of a breach or a change of permissions. Both are important for maintaining security and preventing unauthorized access. There are different ways to handle token expiration and revocation depending on your requirements, such as using short-lived tokens and refresh tokens, blacklists or whitelists, or stateful tokens. Each option has its own advantages and disadvantages, so you should choose the one that best suits your needs and constraints. Additionally, other factors such as token size, encryption, caching, logging, monitoring, and auditing should be taken into consideration when designing and implementing your web API security strategy.
