mongodbHow to create a user in MongoDB?

Creating a user in MongoDB is a simple process.

use admin
db.createUser({
  user: "username",
  pwd: "password",
  roles: [{ role: "readWrite", db: "myDB" }]
})

The above example code creates a user with username and password, and assigns the user the readWrite role on the myDB database.

1. use admin: This command switches to the admin database.
2. db.createUser: This command creates a new user.
3. user: "username": This specifies the username for the new user.
4. pwd: "password": This specifies the password for the new user.
5. roles: [{ role: "readWrite", db: "myDB" }]: This assigns the user the readWrite role on the myDB database.

Output example

Successfully added user: {
    "user" : "username",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "myDB"
        }
    ]
}
