Monthly Quick Tips - May

Hi All! :smile: Back with another installment of monthly quick tips on trending search terms in the community. Here are a handful from the past month:


  • At its core Multi-factor Authentication (MFA) enhances security by requiring multiple forms of verification to access applications. Auth0 supports diverse MFA methods like WebAuthn with security keys/device biometrics, SMS, push notifications, etc., allowing easy integration and customization to strengthen user authentication effectively.

  • PSA :loudspeaker: If you need MFA reset for an admin Auth0 Dashboard account please seeing the following:


  • The audience parameter is used in authentication requests to specify the intended recipient of the issued access token. This parameter is crucial for ensuring that the access token is valid for the specific API or resource server that the client application intends to access. By including the audience in a request, Auth0 can generate an access token tailored with specific permissions (scopes) and configurations that are appropriate for the target API, thus enhancing security and proper access control management.

Refresh Tokens

  • In short, refresh tokens in Auth0 are long-lived tokens used to renew access tokens without needing the user to log in again, ensuring continuous access while enhancing security. Refresh tokens enhance silent authentication by providing a more secure and reliable method for renewing access tokens compared to traditional silent authentication methods that don’t use refresh tokens. Traditionally, silent authentication involves using an iframe to renew tokens, which can be limited by browser security policies like third-party cookie restrictions. Refresh tokens, on the other hand, avoid these limitations and offer a direct, backend process for token renewal, ensuring consistent access even in increasingly stringent browser environments.


  • Logout pertains to terminating user sessions at multiple layers. It involves ending the local application session, the Auth0 session, and potentially federated identity provider sessions. This ensures the user is fully logged out and cannot access secured resources without re-authenticating, providing a comprehensive approach to session management and security.

Too many redirects Safari

  • Review redirect URLs: Ensure that the redirect URLs specified in Auth0 and your application are correct and do not create a loop.

  • Verify your Auth0 application settings, especially the allowed callback URLs, logout URLs, and allowed origins.
