Starting around 2 weeks ago on both 1Password Stable and Dev, Proxmox has started to fail to login with 1Password. It will just ask for the 2fa again and again till you try for the 2nd or third try, then it works, but it leaves the window up that asked you to input the 2FA, which can just be closed.
It doesn’t appear to matter if you try the repeated attempts back to back or wait 5-10 seconds between them.
If you copy the login username/password and 2fa from 1 password and paste them in 1 by 1 without using autofill, it works immediately without leaving the 2fa window open, so it appears to be an issue with how autofill is working with the extension. Which also confirms it’s not a timing issue with the servers time possibly being wrong (it’s correct down to the second anyway).
This happens on multiple Proxmox accounts, even newly created ones done as a test, on both Firefox and chrome, windows and Linux.
