What is OAuth2 token security and how does it work?

OAuth2 token security is a framework that allows applications to obtain limited access to user accounts on an HTTP service. It uses tokens to grant access without sharing credentials.

What types of tokens are used in OAuth2?

There are mainly two types of tokens in OAuth2: access tokens, which are used to access resources, and refresh tokens, which are used to obtain new access tokens.

How can I ensure the security of these tokens?

To secure OAuth2 tokens, you should use HTTPS, implement token expiration, and store tokens securely on the client side.

What happens if a token is compromised?

If a token is compromised, an attacker can gain unauthorized access. It's crucial to revoke the token immediately and issue a new one.

Can you explain the difference between access tokens and refresh tokens?

Access tokens are short-lived and used to access resources, while refresh tokens are long-lived and used to obtain new access tokens without re-authentication.
