GoSafer Security Knowledge Base

This operational reference is organized for GoSafer Security customers and staff. Alarm.com product names are retained where required for technical accuracy.

Overview

Two Factor Authentication is an optional security measure for an account that requires the entry of an additional code, received as an SMS text message or email, after logging into an account with a login name and password. The code can also be generated using an authenticator app. Note: It is recommended to create separate logins for additional users as Two Factor Authentication associates a username with a specific phone number or email address. For more information, see Create a new login.
