About this app

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

Compatibility
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).

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.

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).

No tracking at all, none, zero. Why aren't all apps like this? I have a minor gripe about the language used to describe automatic backups, it says to "external" storage but it isn't it is to internal storage. If you want to backup to external storage (Dropbox Drive etc) you need to do it manually but that's no big deal.

Awesome app, I've used a lot of authenticators over the years, and Aegis of hands-down the best. The UI is fast, clean and practical. The import/ export feature makes switching to a new device easy. More importantly, it is open source with clear accessible code on GitHub, and there are zero trackers and very minimal permissions- meaning this app is great for privacy and security. It's fast, stable and appears to be mostly bug-free. This is now the only 2FA authenticator I recommend for Android

Replaced Authy with this, but kept Microsoft Authenticator for easy sign in, everything else I have Aegis handle. Only thing I miss from Authy is its icon type layout - not a fan of lists, even with the filter option. Be nice to have it auto select an icon for the service or website too rather than just use plain icons, but that's a personal preference. I'll prob change them manually when I have the time. Otherwise great app, keep up the good work!

What’s new

Fixed bugs:
- Icons are now resized to 512x512 to reduce the size of the vault file and to reduce the chance of encountering out of memory conditions
