Atlas User Privileges

Create MongoDB users to provide clients access to the clusters in your group. A MongoDB user’s access is determined by the roles assigned to the user. When you create a MongoDB user, the user is added to all clusters in your Atlas group.

To create a new MongoDB user, from the Clusters view, select the Security tab, then click Users, then Add New User.

MongoDB users are separate from Atlas users. MongoDB users have access to MongoDB databases, while Atlas users access to the Atlas application itself.

Atlas supports a maximum of 100 MongoDB users per Atlas group.

Important

Atlas rolls back any user modifications not made through the UI or API. You must use the Atlas UI or API to add, modify, or delete MongoDB users on Atlas clusters.

Add MongoDB Users¶

1

Go to Users view.¶

To create a new MongoDB user, from the Clusters view, select the Security tab, then Users.

Click Add New User.

2

Enter user information.¶

Field Description

User Name

The user’s login name. All MongoDB users for Atlas are associated with the admin database; i.e. their authentication database is admin. To access MongoDB, a user provides a username and the name of the authentication database, as well as a password. The authentication database does not determine the user’s roles.

You can assign a user different roles in different databases. For example, you can create a user to have the readWrite role on the test database but only the read role on the production database. The authentication database would still be admin.

User Privileges

You can assign roles in one of the following ways:

Select Atlas admin, which provides the user with privileges to administer the Atlas group’s clusters, or
Select Read and write to any database, which provides the user with privileges to read and write to any database, or
Select Only read any database which provides the user with privileges to read any database, or
Click Show Advanced Options and select an individual role/privilege and specify the database. Optionally, for the read and readWrite role, you can also specify a collection. If you do not specify a collection for read and readWrite, the role applies to all collections (excluding some system. collections) in the database.

For information on these privileges, see Atlas User Privileges.

For more information on authorization, see Role-Based Access Control and Built-in Roles in the MongoDB manual.

Password

The user’s password.

Atlas clusters use SCRAM-SHA-1 to authenticate MongoDB users.
