How to add authentication to MongoDB?

At first you need to create an admin user, so bring up a mongo shell by typing mongo in your terminal and hit enter. The database that users are stored is admin, so switch to admin database:

use admin

Now by using createUser database method we will create a user called myUserAdmin:

db.createUser(
   {
     user: "myUserAdmin",
     pwd: "1234qwer",
     roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
   }
 )

Disconnect the mongo shell.

The important note about mongo is to run it by --auth argument, otherwise authentication would not work:

mongod --auth --port 27017 --dbpath /data/db1

#mongodb #mongo #auth #authentication #create_user
