mongodbHow to enable authentication in MongoDB?

MongoDB supports several different methods for authentication.

The most basic authentication method is the MongoDB Native Authentication, which uses a username and password to authenticate a user.

To enable authentication in MongoDB, you need to create a user with the db.createUser() method.

db.createUser(
   {
     user: "myUserAdmin",
     pwd: "abc123",
     roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
   }
)

The above example creates a user with the username myUserAdmin and the password abc123, and assigns the userAdminAnyDatabase role to the user.

Once the user is created, you can enable authentication in MongoDB by setting the auth parameter to true in the mongod.conf configuration file.
