User Roles and Permissions in MongoDB

Learn to control access in MongoDB using role-based access control, where users are assigned roles with specific permissions to protect data integrity, security, and collaboration.

Why do we control access?

Imagine every employee can change the prices or delete customer data—that's a recipe for disaster.

In databases, controlling access protects our:

  • Data integrity: It prevents unauthorized changes.

  • Security: It keeps sensitive information safe.

  • Collaboration: It ensures team members only have access to what they need.

MongoDB provides a flexible, role-based access control system to help with this.

What are users and roles in MongoDB?

A user is an account that connects to a MongoDB database. Each user can be assigned one or more roles. A role is a set of permissions that defines what the user is allowed to do. MongoDB comes with several built-in roles that cover common use cases.
