Available sign-in methods
Only configured providers are displayed. If a provider button is absent, that method is not supported. Interface language does not change the provider account.
Linking and unlinking
Linking uses the official OAuth flow. The portal never accepts OAuth codes manually. A final working sign-in method cannot be removed when that would lock the account. If an external account is already linked, do not create a workaround profile—use secure account support.
Session management
The security page can end other web sessions and revoke mobile devices. After a password change or suspicious sign-in, end other sessions and review email and sign-in methods.
For takeover, unknown access or loss of every sign-in method, use only the private workflow. Do not post the problem publicly or place codes and tokens in a URL.
