When Multi-Factor Authentication (MFA) is enabled for a Punchh admin account, a verification code is required along with an email address and password in order to log in to Punchh.
These verification codes are provided by a Google Authenticator or Authy app once the QR code for Punchh is added: How do I enable Two-Factor Authentication in the Punchh platform?
If you change your mobile device and can still access the Google Authenticator or Authy account, you should still be able to receive these codes on your mobile device.
If this does not work and you need to reset your MFA credentials, please reach out to Punchh support for assistance.
