Temporary Passcodes

A temporary passcode will allow you to authenticate if you can't use your 2FA device. For example:

  • You will be visiting a testing center where you cannot use your registered device.
  • You've forgotten or lost your device (but you've registered a recovery email address for your account).
  • You will be working somewhere without your device.

To request a passcode: Do you currently have access to your 2FA device?

Note: Temporary passcodes are designed for short-term occasional or emergency use. Each code can be used 100 times and expires after 3 days. You can request a temporary passcode a maximum of 24 times a year.
