Many of you probably share the same problem – You have installed EPiServer on your laptop, you get it up and running and you try to login. You try to use your Microsoft account. You enter MyAccount & Password, but it doesn’t work. Then you try with MicrosoftAccount\MyAccount, but it does not work either.
I don’t know if you can use your Microsoft account with EPiServer, but the far more easier approach is to create a local admin on your workstation. Computer Management => Local Users and Groups => Add user. Then add it to the Administrators group.
Login with the newly created admin account. Problem solved.
