I use Aegis[1] on mobile and OTPClient[2] on my computer, both are regularly backed up on change.
I do not use the TOTP feature in my password manager as feel it will defeat the purpose of 2FA (though I can split it to a new DB in KeePassXC).
For my work, the company uses a proprietary password manager, I just don't install it in any of my personal computing devices.
