Alternatives to Google Authenticator
The barebones TOTP standard
Google Authenticator ranks #7 of 10 in Authenticator apps, with an Alt Score of 55. It is proprietary, free and available on iOS and Android. 8 of 9 checklist rows are verified against a public source.
Anyone who wants a free, no-frills app to generate two-factor authentication codes for their online accounts, on either iOS or Android.
Generates time-based one-time passcodes (TOTP) for any service that supports standard 2FA. Accounts can optionally sync to a Google Account so codes are recoverable across devices. It's free, ad-free, and works without an internet connection once accounts are set up.
Add an account by scanning a QR code or entering a setup key shown by the service you're securing, then use the rotating 6-digit code the app displays as the second factor when signing in.
