Authentication Apps

Learn what authentication apps are, how to use them, and the best apps to use.

Authentication apps generate security codes for signing into sites that require 2-factor authentication upon login. 


Bluelink now uses 2 factor authentication (2FA) to login to Lightrail. With 2FA, users will be asked to enter in a security code generated by an authentication app installed on your mobile device or computer each time you login to Lightrail.
