Multiple sites (e.g. Microsoft) currently ask me to use the passkey to log in after I enter my username, but the passkey doesn't seem to be stored anywhere. I usually will end up scanning the QR code to check if it's on my phone and get a negative answer. Then I have to go through the regular password + 2FA ritual I was already ready to use. After that, I am not given the option to store a passkey on the device I am currently using or on my phone. Process repeats next time. So much fun using passkeys.
I think there are two sites where I can actually log in using them.
I also don't like the way the pop-up is always so automatic and interrupting. Why not a button like other ways to log in?
