A user can be a member of an organization regardless of whether they're on a free or paid plan. They can also belong to multiple organizations.
Every person who uses GitHub has their own user account. These accounts include:
- Unlimited public repositories and collaborators on all plans
- Personal plans for private repositories
- Ability to add unlimited repository collaborators
- It may be tempting to have more than one user account, such as for personal use and business use, but you only need one account.
- User accounts are intended for humans, but you can give one to a robot, such a continuous integration bot, if necessary.
Organizations are great for businesses and large open-source projects that need multiple owners and admins. They include:
- Unlimited public repositories on all plans
- Business plans for private repositories
- Team-based access permissions
- Unlimited owners, administrators, and collaborators using teams
- Billing receipts that can be sent to a second email address
- Owners team access to organization members' two-factor authentication (2FA) status
