Logging In with Two-Factor Authentication Enabled

Once you’ve successfully entered the code, the login process is complete.

Notes

Keep your smartphone with the authenticator app in a safe place.
If you switch devices or lose your device, contact your BIG administrator or support so that two-factor authentication can be reset.
Using an authenticator app is recommended over SMS, as it is more secure and works independently of the cellular network.

Two-factor authentication (MFA) enhances the security of your BIG user account. In addition to your password, you will be asked to enter a one-time, six-digit security code when logging in. This code is provided either through an authenticator app or via text message.
