Do they typically not? My only contact with passkeys has been the 2FA service (Duo) at my place of work, and I've got a passkey on my phone and laptop, as well as OTP push notifications, OTP SMS, or recovery code from IT. It's particularly handy with the Chromeboxes hooked into the big presentation displays since I can scan a QR code with my phone to use the passkey stashed inside it.
