Multifactor authenticator recovery to access github and Amazon Services

Question

I lost my old device that was not backed up by Authenticator. I would like to recover these accounts to the new device.

Answer 1

Recovery codes can be used to access your account in the event you lose access to your device and cannot receive two-factor authentication codes. Recovery code is made available to download when setting up the MFA first time for GitHub. If you would have downloaded the recovery code, you should be able to reset the MFA.
