Cannot enable "Log in with passkey" using Bitwarden Lite

[mu88]

Dear community,

I’ve been running Bitwarden Lite v2025.12.0 on my Raspberry Pi 4 fine for several months.

Now I want to try the Log in with passkey feature to log into the Bitwarden web app using a passkey. But when clicking on Turn on and entering my master password, an error pops up:

When checking the browser dev tools in MS Edge, I see the following error:

console-log.service.ts:51 
 SecurityError: The relying party ID is not a registrable domain suffix of, nor equal to the current domain. Subsequently, an attempt to fetch the .well-known/webauthn resource of the claimed RP ID failed.

Any idea what I’m doing wrong?

Thx!

There is another thread around this (but with an error message you don’t seem to get): Activation of passkeys triggers unhandled server error

I would follow that thread – and probably also the GitHub issue and contact BW support.

Thank you for your help!

Unfortunately, it was a typical layer 8 bug I’ve recently reorganized my network layout and forgot to update the BW_DOMAIN env var. After fixing this, it works smoothly.

Ah, thanks for the update! And good to know it works now.
