Update 6/22 (2:15 P.M PST): We have a lot of feedback coming in from the community on this topic. This change will not have any impact for another 90 days at the minimum. We are reviewing your feedback and will discuss further how to achieve our goal of improved security of We will have an update within the next 45 days. To continue the dicussion, we have openend a new GitHub issue here.

EDIT – Updates on this feature is available here – Changes to Expiring API Keys is growing blazingly fast. The past couple of years have seen a tremendous growth in the usage of packages from the NuGet gallery. It’s important to us and the community that package consumers are able to trust and use the packages that are uploaded to Making your API key on more secure is one more step in that direction.

When publishing packages to from the command line, for example using nuget.exe, you need an API key so that we can authenticate the publish operation on the server side. Starting today, this API key will have to be refreshed at least every 90 days. We are introducing API key expiration as a means to keep your API key on shorter-lived.

What does this mean for me?

Today, no action is required. To avoid a big rush when the API keys first expire, we have set the expiration for your current API key to a value between 90 and 110 days.

When the API key expires, it can no longer be used for publishing packages to At this point, your API key will have to be regenerated from your account page.

How do I know when my API key expires?

From your account, you can consult the date and time when your current API key will expire. When approaching the expiration date, we will send one e-mail informing you about the fact your API key is about to expire.
