## Adding MFA with Secret Key Backup

When you first access the Vectra AI Platform, you will be prompted to set up multi-factor authentication on your mobile device. A prompt will appear to scan a QR code that contains a secret key.

Once the QR code is scanned, linked to your authenticator app, and the six-digit code inputted into the Vectra, you will receive a secret key. This secret should be saved to provide a backup for creating a different authenticator app for the user.

To use the Secret Key to register a new authenticator app, manually add the saved secret key when prompted in the app. The opportunity to register by secret key is prompted in the same flow as when a QR code is scanned. Account names are to help track what the key should be associated with.
