Trying to discover new/unheard Linux desktop programs (Sorry for the confusion).
Edit: I apologise for confusing a lot of people. I meant Linux desktop “programs” coming from Windows/Mac. I’m used to calling them “apps”.
Edit: 🙌 I’m overwhelmed with the great “programs” people have recommended in the comment section. Thank you guys.
You could try https://2fas.com/ open source mobile application with browser extensions and cloud sync for backups.
Or www.bitwarden.com password manager is also open source and for a small “premium” supports 2FA for mobile/desktop/browser.
