Paid bitwarden has a cloud based totp that I've been using for this reason. Works perfectly.

You don't use phone TOTP? Google Authenticator, etc.

Plenty of TOTP apps that sync (including google)

It's TOTP, a very simple and universal standard, you can use any application you want - many password managers support it as well.

Do you have something against TOTP? Isn't it better than Authy?

TOTP apps are good enough in most cases.

TOTP is bad 2FA. Google supports U2F security keys. Use them.

Google Authenticator is TOTP and you can use any other app.

Could you compare and contrast to Authy, which also offers that functionality?

Authy use their own system, but the app also supports TOTP.
