Trying to use nitrokey as passkey fails

I was trying to set up my nitrokey 3C as passkey for the forum login.

Being logged in, after clicking ‘Add Passkey’ in preferences/security/Passkeys, i re-authenticate with my password.

Then my browser (firefox) tells me to touch my key. The nitrokey blinks and i touch it, and it blinks green.

It aborts with “The passkey registration process either timed out, was cancelled or is not allowed.”
A http response to /u/register_passkey.json is a 401, with response body ‘{“errors”:[“User verification is required.”]}"‘

I tried using firefox (snap) on ubuntu 24.10, firefox on fedora, chromium (snap) on ubuntu 24.10

Is this the right place to ask?
