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

    Free, open source, and a browser extension for multiple browsers so you can use it on any platform? Hell yes.

    Also it's super simple. It just does what it says on the box, no extra crap you don't want.
