In this method, we set the user name is “hello_admin”, password is “hello123” and the roles of the admin user are readWrite, config, clusterAdmin. In this database, we create an admin user using the createUser() method. So to create an administrative user first we use the admin database. In this example, we are going to create an administrative user in the admin database and gives the user readWrite access to the config database which lets the user change certain settings for sharded clusters. In this method, we can create the name, password, and roles of an administrative user. In MongoDB, you can create an administrative user using the createUser() method. To Encrypt the Password During Transmission, Use TLS/SSL In order To Encrypt It. db.createUser() Sends Password And All Other Data to The MongoDB Instance Without Any Encryption.Also, you are not allowed to create users in the local database. The admin user has the privileges to maintain all the users. In MongoDB, the first created user in the database must be the admin user.It takes the same field as the getLastError Command takes. It manages the level of Write Concern for the creation operation. writeConcern: It is an optional parameter. passwordDigestor: It is used to check whether the server or client digest the password.mechanisms: It is used to specify the SCRM mechanisms or mechanisms for creating SCRM user credentials.authenticationRestrictions: Authentication permission of the user.It is generally used when the role is specified in a different database. Or you can specify a document that contains the role and db fields. To specify the roles you can use any of the following syntax: In this field, you use built-in roles or you can create you own role using db.createRole(role, writeConcern) method.
