Passkeys Explained: The End of Passwords (sentientrant.com)

Passkeys are built on the FIDO2 standard (CTAP2 + WebAuthn standards). They remove the shared secret, stop phishing at the source, and make credential-stuffing useless.

But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.

I broke down how passkeys work, their strengths, and what’s still missing

That doesn't sound like a TOTP vs passkey situation though. It sounds like the program just releases the passkey when you give it the fingerprint. There wouldn't be anything stopping the program from generating a OTP and passing that along when you identify with the fingerprint.

I think a big issue is how difficult it can seem to be to get easy access to TOTP codes, like in your example digging up your phone. But that's more of a browser/operating system failure for not implementing a way to generate those codes like they can already store usernames and passwords.
