Passkeys / Firefox / Paypal

Today the updated Bitwarden addon for Firefox arrived which I was waiting for eagerly because of the passkeys support.

I successfully tested it with and wanted to potentially use it with Paypal.
But within Paypal they just tell me that my system does not allow creating a passkey which is wrong because I did it a minute before with

Any idea why that is not working. Is Paypal using another “filter” for supported systems and if so, why?

I deleted my previous post, because PayPal seems complicated. Maybe it is best, when you search for the PayPal “help page” for passkeys yourself. (I’m not sure if they have the same conditions for every region)

E.g. here in Germany, the passkey function is relatively new in PayPal - and my “help page”, if I understand it correctly, seems to suggest, that a passkey can not be created in Windows at the moment, but on Mac/iOS with Safari or Android with Chrome.

I don’t know the reasoning of PayPal for this…

Was this using Firefox on Windows? PayPal is only supporting passkeys on mobile devices and only using certain browsers for whatever reason. This is from their website:

Today, passkeys for PayPal are supported by Safari and Chrome web browsers on Apple devices running iOS 16, iPadOS 16, macOS Ventura and Google devices running Android 9+. Passkeys are not supported on web view browsers and Windows devices. On a Windows device, the user must use a password or SMS OTP to log in.

Yeah, I’m not sure what is going on. I’m using Fx on Fedora Linux, was able to create a passkey on Github and Google, but when I try on Kayak and Paypal, it says that Fx doesn’t support passkeys, which is obviously incorrect. Does anyone know what is going on? Seems a bit concerning that some sites are actively excluding Fx from this functionality and demanding you use Chrome or a Chrome-a-clone.
