Users & Roles Commands

MongoDB provides flexible role-based access control. Learn to create users, assign built-in roles (read, readWrite, dbAdmin), create custom roles, and enable authentication.

Pro Tips

Create admin users in the 'admin' database. Other users can be created in their target database.

Use built-in roles (read, readWrite, dbAdmin, userAdmin) before creating custom roles.

MongoDB 6.0+ uses SCRAM-SHA-256 by default. Ensure clients support it.

Common Mistakes

Create an admin user BEFORE enabling --auth, or you'll be locked out.

The localhost exception only works once. After creating the first user, all connections require auth.
