What are the different token types in OpenID Connect?

In OpenID Connect, the main token types are ID tokens, access tokens, and refresh tokens. ID tokens are used to authenticate users, access tokens are used to access resources, and refresh tokens are used to obtain new access tokens.

Can you explain the purpose of each token type?

Sure! ID tokens contain user identity information and are used to verify the user's identity. Access tokens allow access to protected resources, while refresh tokens are used to get new access tokens without requiring the user to log in again.

How long do these tokens typically last?

ID tokens usually have a short lifespan, often around 5 to 15 minutes. Access tokens can last from a few minutes to several hours, while refresh tokens can last longer, sometimes days or weeks, depending on the implementation.

Are there any security concerns with these tokens?

Yes, security is crucial. ID and access tokens should be kept confidential, and refresh tokens should be stored securely to prevent unauthorized access.
