# Verify Your Identity with a TOTP Authenticator App in B2C Commerce

Register a third-party authenticator app, like Microsoft Authenticator or Google Authenticator, as a verification method for multi-factor authentication (MFA) logins. The app generates a verification code called a time-based one-time password (TOTP).

[Which Salesforce Commerce Product Do I Have?](https://help.salesforce.com/s/articleView?id=commerce.comm_what_product.htm&language=en_US)

1. Download the supported authenticator app for your device type.
    
    You can use any authenticator app that supports the TOTP algorithm (Internet Engineering Task Force (IETF) Request for Comments (RFC) 6238).
    
    Depending on the MFA verification method settings of your organization:
    
    - Connecting a TOTP Authenticator App is required at your next login and is the only (MFA) verification method allowed: proceed to the next step.
    - Connecting a TOTP Authenticator App or another verification method is required at your next login: Click **One-Time Password Generator** to continue to the next step.
    - If you’re logged into Account Manager, and if registering multiple MFA verification methods is an option, you can connect a TOTP Authenticator App in your Account Information: click Add next to Multi-Factor Verification and choose One-Time Password Generator.
2. Using the authenticator app on your mobile device, scan the QR code. Alternatively, click **I Can’t Scan the QR Code** in your browser. The browser displays a security key. In the authenticator app, enter your username and the displayed key.
3. In your browser, enter the code generated by the authenticator app in the **Verification Code** field.
    
    The authenticator app generates a new verification code periodically.
4. Enter the current code.
5. Click **Connect**.
    
    To help keep your account secure, we send you an email notification whenever you add a new identity verification method to your Account Manager account.
