Sign-in help
A saved card is a shortcut to the right character, not a bypass around authentication.
The button asks me to sign in again
This is expected for social cards on Access. Authenticate with the provider shown on the card.
I selected a different account
Return to the provider step and choose the account associated with that card. A different account must not enter that character. To use another account, start its own account-addition flow.
The callback expired or failed
Start a fresh sign-in from Access instead of reusing an old callback URL. If the provider is unavailable or not configured, report the provider name and error code. Never send the callback token or your password.
The page refreshed
Local display history can remain while authentication is gone. Sign in again; do not try to recover an access token from browser storage.
