I use a browser extension from https://authenticator.cc/
While I do not know whether its UX is similar, it does have a sync feature (but not cross-browser), an export feature, can backup its data to Google Drive, can store everything encrypted (but not by default), is recommended by at least one government website (SSS Employer Portal in the Philippines), and is there for a long time. Oh, and it also remembers which site each secret comes from, and hides others.

Project mention: Ente: Open-Source, E2E Encrypted, Google Photos Alternative | news.ycombinator.com | 2024-03-01probably better to look into projects like this one https://github.com/Bubka/2FAuth
Project mention: How long did it take you to learn Elixir before advancing to Phoenix? | /r/elixir | 2023-06-07Go through getting started, maybe pick one of the starter books from this list but honestly the getting started guide probably covers all the same stuff.
I'm using https://github.com/Spomky-Labs/otphp to generate in a PHP Backend automatically TOTPs. Something similiar is probably also available for Python/Javascript/etc.
I use open source Raivo OTP [1] on iOS and then on my computers with Apple Silicon I use the same iOS app instead of their desktop because it sinks better.
