Enable Authentication

To enable the authentication, perform the following steps:

Go to the server where MongoDB service has been installed.
Open the Command Prompt as Administrator and execute the command below:
```
mongosh --host x.x.xx.x1 --port 27017
```
Execute the command below:
```
MongoDBMongoDB Enterprise> use admin
```

Make the following changes in the values before execution:

user:<username >
pwd :<password>

Note:

(Choose any password for the corresponding user for MongoDB authentication.)

MongoDBMongoDB Enterprise> db.createUser(
{
user: "<username>",
pwd: "<password>",
roles: [ {role: "userAdminAnyDatabase", db: "admin”}, { role: "root", db: "admin" }, "readWriteAnyDatabase" ]
}
)
On successful execution, you will get {ok: 1} message.

Make the following changes in mongod.cfg and refer to the screenshot below.
Figure 1. MongoDB Installation – Start MongoDB Service (non-HA) (Cont.)
Restart the MongoDB service on the server.

Re-open the Command Prompt as Administrator and open the MongoDB terminal using the following command:

mongosh --host <IP> --port <Port> -u <username> -p <password> --authenticationDatabase "admin"
For e.g. - mongosh --host x.x.xx.x --port 27017 -u <username> -p <password> --authenticationDatabase "admin"

Connection with MongoDB should be successfully established.
