    It offers the same functionality as other open source TOTP apps, but additionally offers plain-text (unencrypted) and encrypted backups of your configured TOTP accounts. This app also features a dark mode for nicer view. Besides that, the app offers a lot of different icons to apply to every TOTP entry, so you can find your desired entry easier, if you have a lot in total. To make finding the specific entry even easier, you can assign tags to them, as well.
