r/Passkeys

From LinkedIn Help:

"You can set up a passkey on any of your devices. You may create up to 5 different passkeys for your LinkedIn account. Please note you may not see Create a passkey option if your device's operating version is not up-to-date, if you have reached the 5 passkey limit, or if the feature is not available."

I'll also note that the help article is at least 2 years old.

Why would there be a 5 device limit?

Can you force Android to generate a hardware-bound passkey directly on the phone's internal secure hardware (like StrongBox) instead of a synced, multi-device key?

Natively, Android defaults to synced keys via Google Password Manager. I tried KeePassDX, but it also creates a multi-device key.

To clarify, I am not looking to plug in an external YubiKey. I want the phone's own internal hardware to hold a strictly non-exportable, device-bound key.

Is this a hard limitation of the Android Credential Manager API, or is there a workaround or specific app I am missing?

How are passkeys safer than complex passwords with 2FA Authenticator? Are there any circumstances where the latter may be safer than the former?

With Passkeys is their a greater risk of losing access to the account?

And how do Passkeys compare, in terms of safety, to using a hardware authentication device Isuch as a Yubikey)?

As you see with the new ReCAPTCHA, Google and Apple love to coerce us into using their proprietary phones and services; remote attestation is a part of it.

Is there a way to use passkeys without "cloud" services (still share them between devices, but without cloud), without having an Android/iOS, without an invasive client on the computer, with GNU/Linux?

Hello world. Do we know when/if reddit will add passkey support?​​
