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.

Do Not Use - Impossible to Move to a New Device

Jenna0728 on

The app, while seemingly simple to use, lacks the ability to switch devices at all. If you plan to upgrade your device ever, don’t use this app.

No export or cloud options

I get it. Clouds aren't safe or whatever. Where is the option to export my existing tokens though? I can't move any existing tokens to a new device and I might just loose these accounts forever when I reset the old phone.

Bad

One of the last sources for bring value to older devices. iPhone 5 @ 2022 is now able to authorize 2FA from Google, Microsoft and other challenges. Big Thanks to the developer for keeping backward compatibility.

No backup

This app should have an account ,like a gmail and passcode incase someone loses phone ,my phone is lost but the fact is that apps I use authenticator code for can not be accessed again, and no way on earth to login without the code

Very Helpful!

I use this to authenticate my Roblox accounts and It’s very helpful and easy to use. All I had to do was just scan the QR code (very easy to find, it was the plus) I also appreciate that there are no ads so I can enjoy my experience with it.

No longer gives valid codes

tvd26 on

United States

This app worked fine for a while but now every time I try to login to any site and use a code from this authenticator; the site will tell me the code is invalid. I'm using codes that haven't ran out of time. Codes I got because I scan the QR code to implement them into this app. Backup codes work for the sites but no codes coming out of the app are valid. Had to deactivate all my 2fa because I can't use the codes. Not sure what went wrong but now I have to look for a new app.

The ONLY Secure, Private 2FA App

1: Ignore the 1-star reviews from people who don't understand the point of 2FA and the risks (and benefits!) that come with doing it properly. 2: RTFM - minimize the risk! Make an encrypted iTunes backup of your phone after adding keys, or better yet, write down the recovery codes given by sites when you set up 2FA and securely store two copies, one off-site (in case your house burns down - also applies to those iTunes backups). 3: Hooray, you've got great, safe, and easy 2FA without the need for a separate physical security key!!!! Every other top-rated 2FA app I looked at collects info (why????), or worse, offers you the "benefit" of syncing the underlying keys to the cloud, sometimes without even claiming that E2E encryption is used. If you're okay with undermining the whole point of a physically-locked TOTP token so that you won't fret about losing it, then sure - maybe this app isn't for you. Choose a different app, and put your tokens behind another password which could be accessed by anyone anywhere in the world without your knowledge or approval. On the other hand, if you actually care about doing 2FA right, this app is AWESOME! So simple to use, and rightly keeps things as tightly locked as iOS allows. Cannot recommend this shining star in the 2FA landfill enough!!!!! I do have a couple feature requests, but they're not hardly relevant enough to outweigh the fact that this app is the best bet for actual 2FA security: - would love to be able to add more custom details/notes to each entry, and also change the embedded account name displayed in the main view - would also appreciate the ability to export keys encrypted under a one-time password (as well as the ability to prohibit that when adding new tokens, or, for a weaker but more flexible option, a time delay between export request and fulfillment that's enabled/set prior to keys being added), or perhaps - if possible given the keychain system - some documentation on how to extract keys from a decrypted iOS backup. Unfortunately, an iOS bug is preventing me from transferring data into my new phone, and I'm faced with needing to manually swap the 2FA tokens on every site as a result. Still a minor price to pay for the security offered by this app's exclusion of such dangerous "features" though! THANK YOU for doing things right, and packaging them in a lovely interface too :)
