Encryption key support for Confer.to / supporting PRF Encryption with Passkey storage

[eufnis]

Tried to signup so I can use Confer found at Confer.to and got this message: “Your authenticator doesn’t support encryption keys. Please try again using 1Password — some password managers like Bitwarden don’t work yet.”

Does Bitwarden have plans to implement encryption keys? Sounds like I have to use 1Password to get this capability?

If it matters, I am a paying Bitwarden customer wondering if I should switch to 1Password.

Hello and welcome back!

I believe you are referring to confer.to’s passkey for encryption (PRF).

I am not a Bitwarden employee. AFAIK, the storage of Passkey with encryption (PRF) is not on Bitwarden’s roadmap, and it’s not being worked on as part of the open pull requests. There is a feature request that you can vote for:

Support for Storing PRF-Capable Passkeys in Bitwarden Vault

Talking about the implementation of Passkeys where the Bitwarden Extension/App acts as the A in CTAP. (Authenticator) PRF support → For one of my accounts, I have Bitwarden master password in Bitwarden. I was planning on adding my Bitwarden as a “Login with Passkeys” for Bitwarden, but noticed Bitwarden didn’t support encryption for login with passkeys. I would love to see support.

ps:

1. I also note that there is a discussion about this topic in the subreddit as well.
2. I tested this on Edge on Windows and Bitwarden v2025.12.0, and it doesn’t work, although I didn’t set Bitwarden as Windows Passkey provider. The subreddit mod is claiming it works on his iOS and Brave.

I’ve tried this using Chrome in Windows 11, and it does not work. Bitwarden stores the passkey, but it is not a PRF-capable passkey.

 

The same setup (Chrome and Windows 11) readily handles PRF-capable passkeys that are stored on a YubiKey, so the reason that confer.to throws an error message is that the generated passkey is not PRF capable.

I don’t know how u/djasonpenney got this to work, unless this has been developed under the radar for the iOS app only, and released without fanfare. And clearly, Jason misunderstood the Feature Request thread, so it is not impossible that he may have misunderstood other details, as well (such as where his confer.to passkey is stored).

@eufnis Is that a verbatim quote of the error message you saw? As you can see in my screenshot, the error message does not call out Bitwarden by name (at least not anymore).

Another demo showing that Bitwarden cannot create PRF-compatible passkeys:

Confirming it doesn’t work.
First tried on mobile and thought that was the problem, then tried on desktop.
Same error as others.

Definitely not working for me - Linux/Vivaldi. Works with my Yubikey in that browser.
Also need it for Confer.
Thanks a lot.
