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).

Excellent app to keep data under control without any third party involved (which can be an issue the day their service change). Two things are still required to make it perfect though : remote deletion of the vault on demand and git server support to synchronize my other passwords to avoid manual labor. The first feature clearly is the most critical because even though this is encrypted, having more control is always nice. It could also automatically delete after X attempts (toggle).

Thanks for the extended review Lucas. We're happy to hear you like Aegis! We already support Ripple which achieves what you are suggesting. Ripple is a separate app which allows you to send an signal to your device in case of emergency. Aegis is able to delete your vault upon receiving that signal. Please send us an email if we need to elaborate!

Open source, free, no ads, improving, amoled theme (ace), highlighting and darkens the rest when selected (very nice touch), backup possible (thx a lot) , can be used on multiple devices simultaneously (love it)... Euh what else? Maybe a different view than listing would be great because it gets tricky to find the right entry when we have a lot (I like the way authy present it). Automatic icon search (maybe). Remote deletion in case of phone lost/stolen would be very helpful.
