Invalid password in wpmu dev dashboard plugin

Hello! I am experiencing some issues with wpmu dev dashboard, I changed my mail from to, that didnt help. I changed passwords, that didnt help either. Tried in both chrome, firefox and IE, even tried chrome on my phone and safari on the other one.

I can login without any issues on, but using the same credentials on in the plugin doesnt allow me. It merely just spits out :

Invalid Username or Password. Please try again.
