+### Aegis Authenticator
+Aegis is a two-factor authenticator (2fa) app for Android that's free and open source. The killer feature and why I recommend it is that it supports automatic encrypted backups of the database in JSON format. You can unlock the app with a password or optional fingerprint. It supported true OLED dark mode. An alternative app is andOTP but there were [problems](https://news.t0.vc/EQYR/c#williamwchuang1553266688) with the backups' encryption back when I switched to Aegis.
+
+Enabling 2fa on your accounts is essential for security, especially preventing credential stuffing attacks. Backing up your 2fa data is important in case you lose your phone. It saves you having to dig out recovery codes or try and convince someone that you own the account.
+
+You can install it on Android via the [Play Store](https://play.google.com/store/apps/details?id=com.beemdevelopment.aegis) or [F-Droid](https://f-droid.org/en/packages/com.beemdevelopment.aegis).

 ## Devices
 ### ThruNite T1 Flashlight
 This is a tiny rechargeable flashlight that can output 1500 lumens, enough to hurt your eyes if you look directly into it. It has a magnet on the back to stick to things and an optional pocket-hat clip. I liked it so much I've bought three of them and gave one to a friend who then bought himself a couple more.
