What is 2FAS Auth?

2FAS Auth generates the one-time codes you need for two-factor sign-ins, with no account required and data stored on your device. It is free and open source, supports encrypted cloud or manual backups, custom icons and groups, and pairs with a browser extension for quick code entry.

Pros: what 2FAS Auth does well

  • Free and open source
  • No account needed
  • Handy browser extension

Cons: where it falls short

  • Desktop app not available
  • Browser extension needs the phone nearby

Who 2FAS Auth is for

Anyone who wants a private, free authenticator app for their accounts.

Who can skip it

People who already keep 2FA codes in their password manager.
