I heard Amazon allowed passkeys now (I don't use Amazon any more, but I've still got my account for my order history) so I decided to check it out.
In reality, one of these passkeys is the default *Android* provider, and the other is a Yubikey. 0 stars for the passkey interface: the data are wrong, I can't tell them apart, and I have no way to rename them even if I could. Must. Do. Better.
