Is that a thing? Usually those have a fallback to a regular TOTP code.
I use Okta for work because we integrate SSO with it everywhere, but I could technically enter a code every time and swap out the Okta app for the other TOTP app I use.
My company is a MS shop, but they use TOTP as the second factor, and even that is optional. My department uses Okta, which is a completely separate system (we're a weird, separate unit entirely from most of the rest of the company).
