Original answer (May, 22sd 2012)
With Bitbucket permissions, you can grant write access to other users for each of your repositories.
The user that creates a repo is known as its owner.
Only an owner can delete a repo. You can create unlimited Bitbucket public or private repositories.
- A public repository is visible to all bitbucket users.
- A private repository is visible only to its owner and users that owner gives permissions to. This means an unauthorized user cannot clone or view the contents of a private repo even if they know the repo's URL.
Repository owners can grant other users explicit access to the repository.
An owner can allow 5, 10, 25, 50, or an unlimited number of users access to repositories under his or her control.
The owner always counts as one user.
The owner configures the permissions associated with each user with access. bitbucket supports the following permission levels:
- read View the repository contents. All public repositories grant all bitbucket users read permissions automatically.
- write Contribute to the repository by pushing changes directly from a repository on a local machine.
- admin Do everything a repository owner can do, except delete the repository. This means administrators can:
- Change repository settings.
- Add, change, and remove user permissions.
- Give other users administrator access.
