How to disable Sign in to xxx with google.com

I found several topics about how to desactivate this annoying Google popup.

Even the tip from Google does not work or is not enough:

Uncheck feature there: https://myaccount.google.com/connections/settings

But I still got those popups showing in many websites.

It seems you also have to:

open Vivaldi Settings (Ctrl+F12)
click Privacy and Security tab
scroll down to WEBSITE PERMISSIONS
In Global Permissions locate Third-Party Sign-in and select Block instead of Allow

For the moment, it seems that I have stopped those popups from showing up. Crossing fingers.

Today I got that annoying Google popup coming back.
So I went and check the above settings.
They had been reset, maybe by a recent Vivaldi update.
I set Third-Party Sign-in back to Block and I'm free again.
Same method, same effect, it still works!
