Webauthn is a dumpster fire to implement compared to passwords or totp.

I specifically didn't mention WebAuth...

U2F(Yubikeys utilize it) and TOTP are both great options.

even push to login is quite common these days.

You have great options.

For chrome u2f was replaced by webauthn. Regardless, both are hard to implement compared to passwords
