What are the best practices for refresh token security?

To ensure refresh token security, consider implementing the following best practices: 1. Use short-lived access tokens. 2. Store refresh tokens securely, preferably in an HttpOnly cookie. 3. Implement token rotation to invalidate old tokens. 4. Monitor and log token usage for suspicious activity.

Why is token rotation important?

Token rotation is important because it minimizes the risk of token theft. If a refresh token is compromised, rotating it ensures that the attacker cannot use the stolen token for long.

How can I securely store refresh tokens?

You can securely store refresh tokens by using HttpOnly cookies, which prevent client-side scripts from accessing them, or by encrypting them before storage.

What should I do if a refresh token is compromised?

If a refresh token is compromised, immediately revoke it and any associated access tokens. Then, issue a new refresh token to the user.
