10 best two-factor authentication apps on mobile

  • by

Two-factor authentication apps are popular and powerful tools. They let you log into your account with a second line of authentication. Thus, you can keep your accounts secure even if your password is compromised. It’s not an end-all-be-all solution to account security, but it’s so much better than just a password that we happily recommend two-factor authentication to literally everyone.

There are a few decent apps to help out with this. Most of them should follow the standard protocols as well. Here are the best two-factor authentication apps on mobile. We’d also like to give an honorable mention to Duo (Google Play). It’s the hot new protocol service in town, but the app leaves a lot to be desired.
