ANSWERED: What is the Xfinity Authenticator App?

Comcast offers Multi-Factor Authentication using the Xfinity Authenticator app to provide extra layers of security for logging in and accessing most of your Xfinity services. The Xfinity Authenticator app is available in English or Spanish for download on Apple and Android (phones only).

Xfinity Authenticator alerts you when someone attempts to use your Xfinity ID and password to sign in to your account. You can approve or deny the login attempt with a traditional verification code, yes/no button push, one-touch fingerprint ID or facial recognition.

Setting Up the Xfinity Authenticator

  1. Download the Xfinity Authenticator app from the Apple App Store or Google Play.

Adding Additional Xfinity Accounts

If you have access to more than one Xfinity account, each can be added by selecting the three dots in the upper right hand corner and selecting Add another Xfinity account.
Three vertical dots exist in the screen's top right corner;

You will be prompted to sign in with the account credentials and go through the enrollment process.

Adding Third- Party Accounts

The Xfinity Authenticator also supports certain non-Comcast accounts, which can be added on the welcome screen by selecting Use another type of account. Please note that the non-Comcast account you are adding must already support multi-factor authentication.

Non-Comcast accounts can be added by selecting the three dots in the upper right hand corner and selecting Add a different type of account.
Three vertical dots exist in the screen's top right corner;

You will then need to enable multi-factor authentication in the non-Comcast account. You will be given a QR code that can be used to add the account into the Authenticator. Simply scan the QR code with your device’s camera and the account will be added.

If you are unable to scan the QR code, click Enter Key Code instead. You will then be given the option to enter the code manually, as well as enter the name of the account.
Three fields are displayed for Key Code, Provider Name, and Username or Email.
