To allow your users to authenticate to Private Packagist with their Bitbucket Data Center / Server account, you'll first need to create an integration in Private Packagist. This document walks you through the required steps.

Open the Add Integration form

From the organization settings page, select the "Integrations" subtab. Hit the "Add Integration" button on the integrations listing page to get to the form below. To set up a Bitbucket Data Center / Server integration with Private Packagist, start by selecting "Bitbucket Data Center / Server" as the platform, enter the URL of your on-premise Bitbucket Data Center / Server into the base URL field and select OAuth 1 as the OAuth version as seen in the example below.

Submit the form to see the additional information.

Configure Application link

Click on the link to setup an Application Link on Bitbucket Data Center / Server. You will need the "Client Id" and the "Public Key" shown in the form.

For Bitbucket Data Center versions 7.21 and newer, select "Atlassian product" and not "External application" to be able to set up an OAuth1 link.

After you hit the button to create a new Application Link a configuration window may appear. If it does, verify that the url matches the "Application URL for Link" (https://packagist.com) and hit "Continue", otherwise skip this step.

Now setup a "Generic Application". The only field required is the "Application Name". Submit the form to finish creating the Application Link.

Click on the pen icon to the right of the application you just created to edit the Application Link and configure Incoming Authentication.

This is where we will need the "Client ID" and the "Public Key" that were previously generated on the Private Packagist integration form. Enter the "Client ID" into the "Consumer Key" field, make sure the entire content of the "Public Key" field gets copied and the "Consumer Callback" field stays empty. Submit the form and go back to the list of integrations in Private Packagist.

Share the Bitbucket login link

The final step is sharing your organization-specific login link with your users. Look for the "Login link" button next to your newly created Bitbucket Data Center / Server integration on the integrations page, and copy the URL.

This link presents the option to authenticate with your Bitbucket Data Center / Server account and can now be used to log in to Private Packagist.

Configure Bitbucket Server plugins

In case the U2F & TOTP plugin by Alpha Server is installed on the Bitbucket Data Center / Server then you will need to enable the OAuth whitelist otherwise Private Packagist won't be able to authenticate with the Bitbucket Data Center / Server.
