Monthly Quick Tips - June

[tyf]

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

Forms

• Forms for Actions offer a user-friendly method to collect and manage additional data during authentication through customizable forms. These forms are useful for gathering inputs, displaying messages, or prompting users for extra information, especially during registration, login, or other authentication steps. By integrating these forms with Actions, you can create tailored authentication experiences to ensure all necessary user information is collected and processed effectively.

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.

MFA

• 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.

Logout

• 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

This is almost always related to a configuration issue - Be sure to:

• 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.

• For Safari, review the following Knowledge Solution:

Problem statement We have some scenarios where the browser shows “too many redirects” during a web login for the mobile app. This is all handled by the Auth0 SDK and authenticating directly with Auth0 IDP.
