A link between grafana with no 2nd login

I have 2 Grafana servers in different locations and would like to integrate a dashboard from the 1st to the 2nd.
To do this, I simply set a link and it works - great, but a registration with the 2nd server is necessary. But I used the same ticket for both. Can I use this with the link to the 2nd to register so that no login is required anymore?
