eFrontPro, starting with the 4.4 update, offers a variety of 2FA options to choose from, namely SMS tokens, the Google
Authenticator (a special mobile app that generates time - based authentication
PINs for you), as well as an email - based option.
Setting up the Pro with an Office 365 account that's subject to company policies meant we saw a warning they'd be applied, had to create a
PIN of a certain length and then verify identity with the choice of an incoming phone call, text message, or a mobile
authenticator app.
