If you have a hardware token, you can use it to generate a passcode. You can also use a security key. If your organization allows SMS passcodes as an authentication method and you received the passcodes before the authentication device went offline, you can use them to complete 2FA.

Use The Backup Account

If you had set up a backup account, you're on the safe side, and losing your phone should not be a problem. You can use the backup account to access all your accounts and make the necessary security changes.

If your lost phone has Google Authenticator on it, you need to secure your accounts connected to the app by logging in with an alternate method, and resetting the 2FA settings. You should also erase your phone remotely if possible. You can then add Google Authenticator to a new phone and re-link it to your accounts.

You can only enable email as an MFA factor if there is already another factor enabled. Once Email MFA is enabled, users will be prompted to complete MFA with another enabled factor.
