I just tested the authentication against the Telerik nuget server from Xamarin Studio and it's working as expected.
When encountering Nuget authentication problems with Xamarin Studio or Visual Studio for Mac, it's sometimes best to just delete the package source and re-add it (here's a guide
). I recommend before doing this, to just go to www.telerik.com and verify your credentials are correct by logging out and logging back in,
You can also get the nuget package from the downloads page on your account. For your convenience, here is the link
that will bring you to the UI for Xamarin downloads page. There you'll see that you can pick which type of assembly (trial or paid license) and the version.
Underneath, you'll see 3 download files, one to install locally (for PC), one containing the manual installation files (the assemblies and demos) and lastly you'll see a nuget package. You can download the nuget package. Here's a screenshot to help guide you:
