Simple 2-factor authentication

Published by: Matt Rubin

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.

Does the job well

I don’t understand the 1-star reviews. The codes never failed me, and I’ve upgraded my phone with this app and had no issues in transferring… twice. Plus, the developer’s site says no data is collected. (privacy win!) Would like to see a biometric lock (face id/fingerprint) or password/PIN to open the app.

I love this and I actually been using this app since 2023, I’ve had it on my first phone, my second phone and, And now my third phone that I’m using to write this (IPhone 6) And I mainly use this authenticator for Roblox,Fortnite verification, And etc. The only bad thing I don’t like is to get access to my old codes for discord and stuff like that but overall it’s a amazing authenticator and I’m just surprised as you are that I wrote all this 💀

Should warn you when transferring to a new iPhone

Doesn’t store to transfer to a new phone, so I’m screwed trying to two factor into some important accounts.

It Does exactly what it says

Great app, I like the fact that there are no backups created as I have my own backups so I consider that a feature

Ultra Lightweight Authenticator

As described, it just wants to do the one essential thing. However, it is considerate that there is also documentation on how users should manage and take responsibility.

Stupid

This is the 3rd time trying to get this thing to work. Asks for a token. Where do I get that? These authentication apps are the stupidest things. They are not easy to set up. You need a QR code you need a token. Where are these things at?

Doesn’t work

PureAppIsSexist on

United States

I used it before for my Twitch. I got a new phone and wanted to get Twitch in it, but the authentication code didn’t work. I have no clue why. I didn’t change anything. It just stopped working.

Works fantastic for all my 2FA accounts

Only thing missing that I’d like is support for Apple Watch. Granted, I don’t know if Bluetooth transfer of code info would still be secure.
