A backup code is a temporary one-time code used for account validation when a user's two-factor authentication is not available. **Note:** Users can also generate up to 10 backup codes at a time in the Vindicia IDP app to keep and use for themselves as a two-factor authentication method. For more information on generating backup codes in the Vindicia IDP app, see [User Sign In - Vindicia IDP](vindiciaIDPSignInCred). To log in to the Retain Portal using a backup code, do the following: 1. Follow the [Log In Process](portalAccessingVindiciaIDP) up to step 9. 2. On the **2-Step Verification** page, click **Use a backup code**. 2-Step Verification Page 3. Enter your **Backup Code**. 4. Click **Next**. You have successfully logged in to the Vindicia Merchant Portal using a backup code and were redirected to the Portal landing page. If you are using a backup code because you lost access to your preferred MFA method, you must immediately change or update your MFA method.
