'Nuget Package Source is not prompting for credentials

I've added a NuGet Source. It needs credentials but when I'm installing a package using install-package packageName nothing happens. I tried the same steps on other PC and it works. I'm using Visual Studio 2017 Professional. Could someone please help me with the issue? My NuGet sources

Solution 1:^[1]

This is riddiculous that it does not prompt for credentials.

To make it work I had to do the following:

Download nuget.exe from Nuget download site
Remove my old package source

Go to NuGet Package Manager for Solution->Settings

Delete your Package Source

Run Command Line

Go to nuget.exe

Add package source with plain password in the command

nuget.exe sources Add -Name "YourPackageName" -Source "YourPackageAddress" -Username YourUserName -password YourPassword -StorePasswordInClearText

Done... phew

If Visual Studio does not prompt for credentials but the logging Output shows that you did not authenticate correctly, then go to

Control Panel\User Accounts\Credential Manager

and click "Windows Credentials". You can remove stored credentials for nuget/github there. If they become invalid - for example because you regenerated a token - Visual Studio does not prompt to overwrite the invalid credentials, but after removing the credentials and restarting Visual Studio you do get the prompt.

I've documented more troubleshooting related to the NuGet.Config in this issue: https://github.com/verybadcat/CSharpMath/issues/168

After many attempts to set password, reset password or whatever the only thing that helped me was adding this section to the NuGet.Config (located on the .nuget folder for the main solution)

NuGet.Config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <solution>
    <add key="disableSourceControlIntegration" value="false" />
  </solution>
  <packageSourceCredentials>
    <MySourceName> <!-- Name of nuget package source -->
      <add key="Username" value="..." />
      <add key="ClearTextPassword" value="..." /> <!-- This is for normal password-->
      <!--if encrypted use key="Password"-->
    </MySourceName>
  </packageSourceCredentials>
</configuration>

One important notice - for any change to this file to take effect I had to restart VS

Remove the source from the Nuget Package Manager and add it with a new name.

Solution 5:^[5]

Credentials popup might be not coming because you have earlier entered some other credentials or some other credentials is stored against the NuGet Package. You can goto Credentials Manager in your PC and check for all NuGet Credentials. If you found any, Please remove them from there. And, then try to restart Visual Studio and enter the package source and Url again. This time you will get the popup to add credentials for sure.
