This error only happens on local development environments, whilst running multiple websites on a single hostname. E.g. localhost

This is the default configuration for Visual Studio and IIS Express.

As such, when working on 3 projects you would have:

localhost:10000 localhost:20000 localhost:30000

Same host, different ports.

Because of this each web application can see the others cookies.

To resolve the issue, clear the cookies in the browser.

This is worth considering for any website running on localhost.
