Using a secured package source like the https://nuget.telerik.com/v3/index.json requires you to enter login credentials in Visual Studio. This happens the first time you try to restore a package from the source. After that the credentials get stored in the Windows Credentials Manager app, under the name VSCredentials_package_source or package_source (ex: VSCredentials_nuget.telerik.com or nuget.telerik.com).
When the user credentials change you will need to manually clear or edit the corresponding entries in the Credential Manager. The following steps describe how to edit your nuget.telerik.com credentials.
- Open the Credential Manager app and select the Windows Credentials menu.
- Find the following entries and expand them -
