Passkey setup

Hi, I have seen mention of people using passkeys for ebay login on here but I can't find any way to set one up, can any one help.

For some reason ebay is constantly wanting me to do full login all the time recently.

Fingerprint log in.

Easy enough to set up, but on dome occasions it will still want password.

I have win hello with finger print set up on PC but I have never seen anything about using that with ebay login, can you tell me any more?
