account?

optional account: AccountCallback;

Receives the full TokenSet returned by the OAuth provider, and returns a subset. It is used to create the account associated with a user in the database.

You need to adjust your database’s Account model to match the returned properties. Check out the documentation of your database adapter for more information.

Defaults to: access_token, id_token, refresh_token, expires_at, scope, token_type, session_state

Example

import GitHub from "@auth/core/providers/github"

allowDangerousEmailAccountLinking?

optional allowDangerousEmailAccountLinking: boolean;

Normally, when you sign in with an OAuth provider and another account with the same email address already exists, the accounts are not linked automatically.

Automatic account linking on sign in is not secure between arbitrary providers and is disabled by default. Learn more in our Security FAQ.

However, it may be desirable to allow automatic account linking if you trust that the provider involved has securely verified the email address associated with the account. Set allowDangerousEmailAccountLinking: true to enable automatic account linking.
