How do I authenticate to NuGet?

source

Interactive authentication option

1. install the credential provider

wget -qO- https://aka.ms/install-artifacts-credprovider.sh | bash

this will place the nuget configuration here: /home/<user>/.nuget

2. restore packages interactively

dotnet restore --interactive  (will now ask you to do a device login)

this will prompt you for a device login flow

Configuration file option

Configure the nuget.config file as follows:

placeholder $NUGET_UID} is a user login and ${NUGET_PWD} is an associated PAT which has access to packages
