JWT questions

To handle JWT expiration, set an expiration time when issuing the token and verify it on each request. Use refresh tokens to obtain a new JWT without requiring the user to log in again. Store refresh tokens securely and use them to request a new JWT from the server when the original token expires. Implement token rotation to enhance security.

JWT tokens should be stored securely on the client side to prevent unauthorized access. Use `HttpOnly` cookies to store tokens, which prevents JavaScript access and mitigates XSS attacks. Ensure cookies are also marked as `Secure` to be sent only over HTTPS. Avoid storing tokens in local storage or session storage, as they are vulnerable to XSS attacks.

Handling JWT token storage on the client side requires careful consideration to ensure security. Common methods include storing tokens in HTTP-only cookies to prevent JavaScript access, which helps mitigate XSS (Cross-Site Scripting) attacks. Alternatively, tokens can be stored in secure storage mechanisms such as localStorage or sessionStorage, but this approach may expose tokens to XSS risks. Always ensure that tokens are transmitted over HTTPS to prevent interception and that they are managed with appropriate expiration and renewal policies.

To ensure the security of JWT tokens during transmission, use HTTPS to encrypt the data exchanged between clients and servers. This prevents eavesdropping and interception of tokens. Additionally, protect tokens from exposure by using HTTP-only cookies for storage, which helps mitigate XSS attacks. Implement proper token management practices, such as regular token rotation and secure token storage, to further enhance security. By combining these measures, you can safeguard JWT tokens against unauthorized access and ensure their integrity during transmission.
