    Replying to an older comment: it applies icons via an icon pack, which it links in-app as a download if you want it

    Simple yet effective OSS authenticator app. Encrypted database, local/cloud backup; other security features much better than corporate options. Default icon pack could be included and auto-assigned, but better than nothing.

    Of course can you use KeePass and apps that utilize kdbx files as a TOTP generator. Just read it up.

    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.

    I like it because it is open source. It has good features. More secure. And doesn't have useless features unlike google auth while has more good features.

    Keepass2Android supports TOTP. The better thing is, TOTP seed works with desktop applications too. Therefore, you need only one database for desktop and mobile devices. Also, built-in Keepass keyboard allows autofill all inputs from one place, you don't need to switch between applications.
