An easy-to-use, open-source two-factor authentication app designed specifically for iOS.
Tofu generates one-time passwords to help you protect your online accounts. These passwords are used together with your normal password when you sign into services like Google, Facebook, Dropbox, Amazon, and GitHub.
Tofu works with all services that provide two-factor authentication using the HOTP and TOTP algorithms. It does not require a network or cellular connection and can be used in airplane mode.
- Scan the QR code your issuer provides to automatically add your account.
- Search your accounts by name to quickly find the one you're looking for.
- Support for both counter-based and time-based one-time passwords with 6 or 8 digits using the SHA1, SHA256, and SHA512 algorithms.
- Requires no network or cellular connection and can be used in airplane mode.
- All your account details are safely stored in the iOS keychain.
Tofu is open source and free software licensed under the ISC license. The source code is available for review and modification on https://github.com/calleerlandsson/tofu.
- New issuer icons.
Ratings and Reviews
Best 2FA app
This is the best two-factor authentication app I’ve used! It’s clean, neat, and beautiful. The account icons make it easy to find accounts and make using the app a pleasure. I can see 10 accounts on the screen at once (Max model), which is a lot more than the previous app I was using.
It also doesn’t track you or collect any information, which is great. It’s open source too.
Now the developer just needs to add a way for people to tip him on his website!
For those looking for Google alternatives!
This app has been flawless for me up until recently when I had to upgrade phones. All my 2fa setups evaporated. However, trust is big in this digital world and I’m going back in hopes the developers get that fixed! Thanks for your hard work!
Great, simple app, but some major concern
This is the best 2FA option I’ve found so far. It’s to my taste: simply designed, unobtrusive and it just works. I did have some concerns though…
I’m not really sure if it has any iCloud backup functions or syncing capabilities. It makes using and relying the app feel precarious because I’m never sure if for whatever reason I lose or brick my phone whether or not my keys will be there.
I would really like some ability to save/sync my keys in the future, or at least some assurance that it’ll always be tied to my iPhone.
Besides that, some options in settings and additional configuration would be great. It feels a little *too* bare.
Please consider, devs!
