 :::info Important
 
-Some login methods (like Twitch and Discord) cannot be combined with others because they lack a
-**common identifier**, such as an email. This identifier is crucial for connecting user accounts
-across different authentication methods and ensuring reliable user recognition when switching
-between login methods.
+- **Twitch** and **Discord** can only be aggregated with themselves (self-aggregate).
+- **Google** and **Email Passwordless** can always be aggregated with each other.
+- **Google** and **Email Passwordless** can also be aggregated with Auth0, Custom JWT, AWS Cognito,
+  and Firebase providers, but only when the JWT user identifier is set to email.
