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).

I've started to use this in 2025 and I'm still using it. I've had no problems with it. This is all I ever wanted, something like BitWarden but an authenticator. These two pair well together and if you don't mind depending on a Master Password that you must write down or keep safe elsewhere, then I strongly recommend this! 😁

Compared to other 2FA app, this is straightforward in usage but it is only for Android OS. One irritating issue is it forces one to sign in using password once a week at unspecified timing. It can happen when one is in a rush or in a situation where one does not want to reveal one's input password to those around oneself. It'll be better to have the user input password anytime safe for him or her as long as it is input once a week or once every 2 weeks.

Thanks for the review Ken. As for the password reminder, you can either disable it or change its frequency in the settings. Also do note that you can still bypass the password reminder by tapping 'Biometrics' underneath the password field whenever it happens. Hope this helps!

The best authenticator app. Open sourse, no ads, full control, import or export from other apps. Password protected, and the best is easy backup that can be saved anywhere. Couldn't find a better app with all these features. EDIT 2024. More than a year of usage, and couldn't be more satisfied. Zero issues. Wish there were a 6 stars rating.
