Database Users

MongoDB uses database users to authenticate clients and grant access to your deployment. Assign roles to database users based on the level of access and tasks they need to perform.

Create database users to:

  • Allow reads and writes to the database but restrict administrative access.

  • Assign administrative privileges to manage the database, perform backups, and configure settings.

  • Grant read-only access for reporting and analytics.

Roles govern database user permissions. Use MongoDB's built-in roles or create custom roles.

Grant database users in self-managed deployments one or more roles. Roles grant users privileges to perform actions on specified resources.

Users can perform actions on the following resources:

  • Collections

  • Databases

  • Clusters

To create and manage users in your self-managed deployment, use the createUser command or the db.createUser() method.

Database users in MongoDB Atlas have different built-in roles than self-managed deployments. When you create a database user in MongoDB Atlas, Atlas built-in roles apply to all databases in your project.

Note

Database users are separate from Atlas users. Database users access MongoDB databases. Atlas users access the Atlas application.

Create database users, assign built-in roles, and create custom roles in the Atlas CLI, Atlas Administration API, or the Atlas UI. To learn more, see Add Database Users.

To create and manage database users, see:

Specify the authentication mechanism when you create a user. MongoDB supports the following authentication mechanisms:

SCRAM
X.509
Kerberos
LDAP
OIDC
AWS-IAM

MongoDB Community

MongoDB Enterprise

MongoDB Atlas (M10 and above)

MongoDB Atlas (Free and Flex Tiers)

MongoDB Atlas (Flex)

MongoDB uses Role-Based Access Control to verify user access to resources and operations. Database users in MongoDB Atlas have different built-in roles than self-hosted deployments. However, MongoDB builds all built-in roles from the same set of privilege actions.
