Aegis Authenticator

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

Meet Aegis Authenticator

Aegis is an alternative to proprietary two factor authentication apps like Google Authenticator and Authy. Its most important features, are security and backups.

Encryption

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).

Organization

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.

Backups

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.

Wonderful new 2FA app! I've been looking for one with password security and the ability to use the phone's fingerprint sensor to open.

The app is the new player on 2fa market. Love that it's open source and comes with more secure encryption out of box than competitors. Devs are super active and responsive to the feedback.

Frequently Asked Questions

  • What does your app offer that other 2FA apps do not?

    Compared to other 2FA apps, we think Aegis stands out in terms of its simplicity and security. Most popular apps like Google Authenticator and FreeOTP don't bother with additional security measures. They allow access to your tokens right after opening the app. Aegis, on the other hand, encrypts all of your tokens at rest and requires a password or the touch of a finger to decrypt them.

    Another important feature is the ability to export your tokens and import them into another device. Google Authenticator doesn't have this, which has not only annoyed users for years, but has also resulted in loss of access to lots accounts.

  • Can you implement feature x and y?

    Maybe! We certainly welcome feature requests and we make sure to consider every one of them. However, as we work on this app in our spare time, we can't make any promises as to when or if it will make it into the app. We usually work on the features we would like to have ourselves, so if you'd like to see a feature sooner rather than later, the fastest way would be to contribute! We're happy to help you in the process. The code is available on GitHub.

  • I found a bug! Where can I report it?

    Yikes! We track all issues and feature requests on GitHub. Please submit an issue there. If you prefer, you can also send us an e-mail.

  • Can I support your work?

    Yes! We take donations on Buy Me A Coffee, in case you'd like to send a few dollars our way. There's also an even better way you can help out, by contributing! All of the code is free and open source, so you can grab a copy of it from GitHub and start hacking!
