Hi When in development I can sometimes open up 2 solutions. If I do this and log in to the back, on both solutions one of them gets logged out automatically. I'm assuming it's a cookie somewhere that needs to be set to a different name, does anyone know how to go about this?

Side note: If you can use a hostname other than

localhost

, this would work automatically. The "problem" is that

localhost:40000

and

localhost:40001

share browser security context.

there is an appsetting to allow multiple logins..

AllowConcurrentLogins

https://docs.umbraco.com/umbraco-cms/reference/configuration/securitysettings might help?
