Looks like a huge amount of security vendors are working to have a secure and open standard for passkey portability between platforms.

It is always good to see major collaboration in the security space like this considering the harsh opinions that users of some of these vendors have toward many of the others. I just wish apps and sites would stop making me login with username and password if passkeys are meant to replace that lol.

I don't like that passkeys are portable, this kind of defeats the entire purpose. The way they were sold to me is the following: it's 2 factors in one. The first is the actual device where the key lives, and the second, the user verification, like a pin, face scan, fingerprint etc. If it's synced across the cloud, there's no longer the first factor being the unique key on the unique device.

Granted, passkeys even without the first factor are still magnitudes better in terms of convenience and security compared to passwords, but it just disappoints me a little that there are no good options to save passkeys on my local device only, with no cloud sync.

If anyone knows of a local-only passkey manager app for android, as well as the same as a firefox extension, I'd love to know about it!

If they're not portable how would I for example login to an account while on my Desktop, if I set up the passkey on my Phone?

There are already systems in place that allow temporary passkey sharing, for example with a QR code (CaBLE) https://www.corbado.com/blog/webauthn-passkey-qr-code

Doesn't that imply you still have to open up your phone to temporarily share to your pc whenever you need it?

Yes but when you are logged in, you can add the passkey that belongs to the new device to your account
