About this app

Aegis Authenticator is a free, secure and open source app to manage your 2-step verification tokens for your online services.

Aegis supports the HOTP and TOTP algorithms. These two algorithms are industry-standard and widely supported, making Aegis compatible with thousands of services. Any web service that supports Google Authenticator will also work with Aegis Authenticator.

Encryption and biometric unlock
All of your one-time passwords are stored in a vault. If you choose to set a password (highly recommended), the vault will be encrypted using strong cryptography. If someone with malicious intent gets a hold of the vault file, it’s impossible for them to retrieve the contents without knowing the password. Entering your password each time you need access to a one-time password can be cumbersome. Fortunately, you can also enable biometric unlock if your device has a biometrics sensor (i.e. fingerprint or face unlock).

Over time, you'll likely accumulate tens of entries in your vault. Aegis Authenticator has lots of organization options to make finding the one you need at a particular moment easier. Set a custom icon for an entry to make it easier to find. Search by account name or service name. Have a lot of one-time passwords? Add them to custom groups for easier access. Personal, Work and Social can each get their own group.

To make sure you will never lose access to your online accounts, Aegis Authenticator can create automatic backups of the vault to a location of your choosing. If your cloud provider supports the Storage Access Framework of Android (like Nextcloud does), it can even create automatic backups to the cloud. Creating manual exports of the vault is also supported.

Making the switch
To make the switch easier, Aegis Authenticator can import the entries of lots of other authenticators, including: Authenticator Plus, Authy, andOTP, FreeOTP, FreeOTP+, Google Authenticator, Microsoft Authenticator, Steam, TOTP Authenticator and WinAuth (root access is required for the apps that don't have an option to export).

Simple yet secure. Does everything you need it to do, without being bloated down by ads or unnecessary features. Best of all, you can back up your 2FA vault to an encrypted file, which you can also use to access your codes from another device if you wish to. That was exactly the functionality I had been looking for, so that my codes remain secure, yet still accessible from multiple devices just in case. UI design is very clean as well, and completely free. I definitely reccommend.

By and large I really like this app. The one issue I have is that my preferred login method, biometric, is hidden by the keyboard on my phone. I don't know if this is intentional or because the UI was designed for larger displays. It'd be great if there was an option to make biometric the default as well as making it so it doesn't require multiple gestures to access when it isn't the default. Edit: The developer responded and it looks like there's a way around said issue. Which is great! Going to move to 5 stars. It's a free (and great) tool so I don't want to be overly critical. It looks like other people have had this issue before as well so perhaps the UI should make it clear that this is a one time thing that will go away once you enter your pin.

Thanks for your review. You're probably seeing the password reminder. Try entering your password once. After that, Aegis will prompt for biometrics by default again until it's time for another password reminder.

Came over from andOTP, since it appears to be unmaintained. All of my entries were easily added into Aegis by scanning QRcodes. Very nice user experience. One feature I would like to see in the future is a way to visually see when the code is about to change. Some authenticators have a countdown or progress indicator. andOTP changes the color of the numbers to red shortly before they expire. Otherwise, this is a perfect app.
