Set up verification and troubleshoot account access
Enable SMS protection, handle missing codes and use the recovery options actually available.
Enable SMS two-step verification
In Account, open Sign-in & security and choose Set up beside SMS two-step verification when available. Confirm a verified email first, then verify the phone with the code sent to it. Follow any identity recheck requested before the number is enabled as a second factor. Saving a contact number is not the same as enabling this protection.
Open AccountWhen a code does not arrive
Check the destination and country code. For email, check spam and filtering; for SMS, check reception and whether the number can receive messages. Wait for the resend countdown, request a new code once and use the latest code. Availability may depend on the phone country and service settings. Repeated requests can be limited.
If you cannot complete sign-in
If shown for your enrolled account, use an authenticator code or an unused backup code instead of SMS. Google sign-in is only an alternative when it is already connected to the same account; it does not bypass required verification. The current Twelva sign-in form does not offer self-service password-reset email. Contact support if you cannot use the offered methods.
