Add a Developer User to Your Dev Hub Org

Using a Developer license, add a user with the Developer profile and assign them the Developer permission set.
The Developer license is a paid license that is designed for users whose role is to build customizations or applications. This license provides access to development tools and environments. It comes with one Developer sandbox, one scratch org, and access to the Dev Hub. In the production org, this license restricts access to standard and custom objects.
  1. Create a user in your Dev Hub org.
    1. In Setup, enter Users in the Quick Find box, then select Users.
    2. Click New User.
    3. Fill out the form.
    4. Select Developer for User License, and then Developer for Profile.
    5. After filling out the remaining information, click Save.
  2. Assign the built-in Developer permission set to the user.
    1. On the user's detail page, in the Permission Set Assignments related list, click Edit Assignments.
    2. In the Available Permission Sets, add the Developer permission set and click Save.

The Developer permission set grants access to Dev Hub features and second-generation packages. For details, see Create and Assign a Permission Set to Developer Users.
