Description

Authenticator is a simple, free, and open source two-factor authentication app. It helps keep your online accounts secure by generating unique one-time passwords, which you use in combination with your other passwords to log into supporting websites. The simple combination of the password in your head and the rotating passwords generated by the app make it much harder for anyone but you to access your accounts.
• Easy: Simple setup via QR code, "otpauth://" URL, or manual entry
• Secure: All data is stored in encrypted form on the iOS keychain
• Compatible: Full support for time-based and counter-based one-time passwords as standardized in RFC 4226 and 6238
• Off the Grid: The app never connects to the internet, and your secret keys never leave your device.

Authenticator Reviews

Great in (mostly) every way!

HelloOpenSource1 on

Great app, however there are 2 features missing to make it perfect. You cannot export the OTP details to another app, like to migrate to a PC based app, or unlock the database via password or biometrics. Otherwise amazing!

Perfect

My favourite Authenticator app on iOS

How simple this is

This is not hard and does not cost money which is extremely good and it is very simple.

One weakness

Tonyteehee on

United Kingdom

The app itself should require a fingerprint or password to open it just in case the phone gets nicked. Let’s be honest fraudsters will go to enormous lengths to gain access to you data. Fingerprint requirement would add another tier Also doesn’t appear on Last pass list

Yeet

Best one I have got for 2fa

Only TouchID would improve it

Great little tool, but an extra layer of security to access the generated codes would be the cherry on the icing.

Doesn’t work
