I was working on a project in Graphite Studio located in Azure DevOps with my company's credentials. When I tried to open a project in another Azure DevOps organizations using a different User/Password combination I get the following error.

Exception is: TeamFoundationInvalidAuthenticationException - We were unable to establish the connection because it is configured for user First.Last@Company1.com but you attempted to connect using user First.Last@Company2.com. To connect as a different user perform a Switch user operation. To connect with the configured identity just attempt the last operation again.
