Best Practices for Setting Validity Period
When setting the validity period of JWT tokens, consider the following best practices:
- Short-Lived Tokens: Prefer shorter-lived tokens to minimize the risk of unauthorized access in case of token leakage or compromise. Typical expiration times range from minutes to hours, depending on the application’s security requirements.
- Refresh Tokens: Combine short-lived access tokens with longer-lived refresh tokens. Refresh tokens can be used to obtain new access tokens without requiring the user to reauthenticate, mitigating the impact of short expiration times on user experience.
- Dynamic Expiration: Implement dynamic expiration policies based on user activity, session context, or access patterns. Extend the expiration time for active sessions while revoking inactive or suspicious tokens promptly.
- Token Rotation: Periodically rotate JWT tokens and refresh tokens to limit their lifespan and reduce the likelihood of successful token-based attacks.
How Long is a JWT Token Valid ?
JSON Web Tokens (JWTs) are widely used for authentication and authorization in modern web applications and APIs. One crucial aspect of JWTs is their validity period, which determines how long a token remains valid after it has been issued. In this article, we’ll delve into the factors influencing the validity period of JWT tokens and best practices for setting their expiration time.
