Deploying Packages to NuGet Hosted Repositories
In order to authenticate a client against a NuGet repository, NuGet uses an API key for deployment requests. The API key is acts as an alias for the user account, so the same API key is used for all NuGet repositories within the repository manager. This user-specific key is generated separately by a user and can be regenerated at any time. At regeneration, all previous keys generated for that user are invalidated.
