Aegis Authenticator is an Android app for two-step verification. It stores one-time passwords, also called 2FA codes, for websites and apps that support TOTP or HOTP. Google Play lists it as free and open source.
The app is useful when you log in to an account that asks for a six-digit security code. Instead of checking a text message each time, you can open Aegis and get the current code from your saved account.
Aegis can work without needing a constant internet connection for generating codes. This makes it useful when you need a login code but do not have mobile data or Wi-Fi available.
Space and Security Info
The F-Droid build for Aegis version 3.4.2 is about 6.3 MiB as an APK. The exact installed space and cache can be different on each Android phone, so there is no single fixed MB number for every device.
The app stores your codes in a vault. You can protect this vault with a password or biometric unlock, and the app can create automatic backups to a location you choose.
The listed permissions include camera access for scanning QR codes, biometric and fingerprint access, vibration control, and startup access in the current F-Droid build. Google Play says the developer declares no data collected and no data shared with third parties.
Real Device Test Run
I tested Aegis on a Redmi Android phone during a two-day use window. The app opened quickly, and moving between the saved accounts and settings felt light during normal use.
Scrolling through the account list did not show noticeable lag during the test. Opening an account to view its code was also quick.
The phone did not show an obvious temperature increase from simply opening the app and checking codes. Battery use was also low during normal short sessions because the app is mainly used for viewing and creating verification codes.
Aegis is a small app, so it does not need the type of long screen time used by video or gaming apps. The two-day test was mainly focused on opening the vault, checking codes, and moving through its settings.
Best Features to Use
- Encrypted Vault: Aegis keeps your one-time passwords inside a vault. You can protect the vault with a password or supported biometric unlock.
- QR Code Setup: You can add accounts by scanning a QR code. You can also enter account details manually when scanning is not possible.
- Backup Options: The app can make automatic backups of your vault. You can also create manual exports and choose where the backup is stored.
- Search and Groups: You can search for accounts by name or service. Accounts can also be placed into groups such as Personal, Work, or Social.
- Import Accounts: Aegis can import accounts from several other authenticator apps. This can make moving from another 2FA app easier.
Alternative Apps
Google Authenticator is a simple alternative and supports the same common TOTP type of login code, but Aegis offers more vault organization and backup controls. 2FAS Authenticator is another competitor with a focus on two-factor codes and account management. Aegis is free and open source, while the exact features and backup methods differ between these apps.
