Hi everyone,

it seems that the PRF extension is finally supported on recent Windows builds. I’m currently on Windows version 26200.7840, and PRF using Windows Hello is working for me on the following testing sites:

On all of these, PRF works successfully with Windows Hello, which suggests that the underlying WebAuthn/PRF implementation in Windows is now functional.

However, when I register a new passkey with Bitwarden, it still reports that encryption is not supported.

Hello and welcome to the community :waving_hand:

Just adding a note that the aforementioned Windows version appears to be the February 2026 standard patch (stable) release.

This sounds like great news. It will mean Windows users will be able to create passkeys that can be used for encryption in Bitwarden.

I already have a passkey for Bitwarden in Windows but cannot use it for encryption. Once Windows Hello supports PRF, will I be able to mark it for encryption or will I need to delete the passkey and create a new one?

I’m only able to get the last of those 3 websites to work, same version of Windows 11.
