Nuget Package Source is not prompting for credentials - nuget

Question

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

Answer 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:

Answer 3

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

Answer 4

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

Answer 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.
