Atlas offers the following security features for cluster authentication.
To learn about recommendations for authentication, see Guidance for Atlas Authentication in the Atlas Architecture Center.
Database User Authentication
Atlas requires clients to authenticate to access clusters. You must create database users to access the database. To set up database users for your clusters, see Configure Database Users.
Custom Database Roles
When the built-in Atlas database user privileges don't meet your desired set of privileges, you can create custom roles.
Authentication with AWS IAM
You can authenticate applications running on AWS services to Atlas
clusters with AWS IAM roles. You can set up a database user to
use an AWS IAM role ARN for authentication and connect to your
database using mongosh and drivers that authenticate using your AWS
IAM role ARN. Using AWS IAM role reduces the number of
authentication mechanisms and number of secrets to manage.
To learn more, see AWS IAM Authentication.
User Authentication with LDAP
Atlas supports performing user authentication with LDAP. To use LDAP, see Set Up User Authentication and Authorization with LDAP.
User Authentication with OIDC
Atlas supports performing user authentication with OIDC. To use OIDC, see Authentication and Authorization with OIDC/OAuth 2.0.
User Authentication with X.509
X.509 client certificates provide database users access to the clusters in your project. Options for X.509 authentication include Atlas-managed X.509 authentication and self-managed X.509 authentication. To learn more about self-managed X.509 authentication, see Set Up Self-Managed X.509 Certificates.
