As much as I like the Apple Passwords app, one of its downsides is that if I have my TOTP app on my iPhone, both passwords and TOTP live on the same device. So for many services I use Bitwarden for passwords.
replyFor TOTP i use ente auth[0], which i can higly recommend.
replyi also force most apps on iOS to ask for face id (long press on app icon to set this).
