What are the best practices for JWT authentication in ASP.NET Core?

Some best practices include using strong signing algorithms, setting appropriate token expiration times, and validating tokens on every request.

How can I securely store JWT tokens on the client side?

You should store JWT tokens in secure, HttpOnly cookies to prevent XSS attacks, or use secure storage mechanisms.

What should I do if a token is compromised?

If a token is compromised, you should revoke it immediately and issue a new token. Implementing refresh tokens can help manage this.

Can you explain how to implement token expiration?

You can set the expiration time in the token's payload and check it during validation. Use short-lived access tokens with refresh tokens for better security.
