Duo Mobile
Duo’s security services are mainly aimed at businesses, but anyone can make use of its clean, reliable authenticator app—like the other apps we’ve mentioned here, it supports a wide variety of third-party accounts (from Amazon to Snapchat), and set up is as swift and as simple as you would hope (it usually just involves a couple of taps and a QR code scan).
If you’ve got multiple accounts set up inside the app then they’re easy to identify and manage from one master list, and if the services you’re using support push notifications then these can be handled on your phone as well. Plus, if you’ve got biometric security set up on your handset, then Duo Mobile can use this to help verify your identity.
