backup recovery
Use a backup code.
Use one of the codes you saved when you set up your account; each code works once and gets you in without your authenticator app.
Do this once you are in
A used code is gone. Open your account settings to issue a fresh set of backup codes, and to link a new authenticator app if the old one is lost for good.
