Hello,

I installed vaultvarden on my synology NAS with a container. I activated the admin page.

On an account, I tried to put a yubikey key. On the customer account this and accept.

When I try to log in using yubiley, I get an error popping up so I’ll take a screenshot for you.

I think there’s something missing.

Thank you for your help

That is because Vaultwarden doesn’t support this.

Hello  
My message took 2 days to be validated, in the meantime I found the solution  
You had to activate the websocket in the reverse-proxy of the NAS  
In the meantime, I have also activated the YubiKey on the cloud
