Hi @Richkm ,
I'm afraid this is not possible, the SCOM web console requires you to login.
If you want you could create a dedicated domain account used to login for the SCOM web console and give the account access to dashboards, then keep the dashboards open on a monitor with an auto refresh browser extension, so that it doesn't log you out after the timeout period, or simply change the "SessionTimeout" value of the web console's Web.Config file to a higher value.
If you have any feedback about this, you can submit it over here:
