This guide does not apply to most MSDN users because they are not required to own or log into Xamarin accounts unless using the Xamarin Components store or Xamarin Studio (Mac). MSDN license holders should refer to this Licensing Options guide instead.

Overview

There are a few common causes that may prevent you from logging into your Xamarin account in the IDE. Known issues & fixes are described below.

Finding the Login Screen

For reference, the login screens are found here:

  • Xamarin Studio
    • Top right corner of the welcome screen
    • Xamarin Studio > Account (Mac)
    • Tools > Account (Windows)
  • Visual Studio
    • Tools > Xamarin Account

The IDE is connecting, but the account screen isn't showing correct login information

This issue is typically resolved by a manual license resync. Please follow the directions in this article: How do I manually resyncronize Xamarin licenses?

Invalid Account Information

If you go to the Xamarin website login page, you can try logging in with your current account credentials. The page also has links to reset your password and to create a new account.

Account is valid, but the IDE can't connect

This is usually caused when firewall or other security settings block the IDE from accessing needed endpoints. The activation servers must access the following:

activation.xamarin.com
store.xamarin.com
auth.xamarin.com

However, several other endpoints are important for general development processes, such as updates, getting NuGet packages, etc. Because of this, it's recommended to make sure ALL of the endpoints are added from the Xamarin firewall configuration guide.

iOS in Xamarin Studio Windows

iOS developement is not supported in Xamarin Studio for Windows. When accessing the login screen here, the iOS license will not be displayed.

Instead, login via Xamarin Studio (Mac) or Visual Studio with a legacy license. Note that MSDN users on Windows do not need to log in.

Additional Support

If the above scenarios do not describe your situation or resolve the issue, please email the support address shown on your account page, or contact us at hello@xamarin.com.

Xamarin Workbook

If it's not already installed, install the Xamarin Workbooks app first. The workbook file should download automatically, but if it doesn't, just click to start the workbook download manually.
