Changing the Admin Password for MongoDB

Overview​

If authentication is enabled in MongoDB and the admin password is lost, use this procedure to reset it.

IMPORTANT: You must log on to the server hosting MongoDB to complete this procedure.

Instructions​

  1. Stop the MongoDB service using services.msc or sc stop MongoDB.

  2. Disable MongoDB authentication:

    • Navigate to C:\Program Files\NNT Change Tracker Suite\Gen7\MongoDB\bin.
    • Edit the mongod.cfg file.
    • Comment each line out using the # symbol except for logpath, dbpath, net, port, bindIp, and storageEngine.

  3. Start the MongoDB service using services.msc or sc start MongoDB.

  4. Open the Mongo shell by running the following program: C:\Program Files\NNT Change Tracker Suite\Gen7\MongoDB\bin\mongosh.exe.

    Mongo shell open and ready for commands

  5. Enter the following commands in the Mongo shell, in order:

    use admin
    db.changeUserPassword("admin", "<YourAdminPassword>")

    NOTE: Replace <YourAdminPassword> with the new password you wish to use.

    Changing the password returns you to a new line without an output.

  9. Open Command Prompt and verify your Mongo logon using your authentication command. The following is an example:

    "C:\Program Files\NNT Change Tracker Suite\Gen7\MongoDB\bin\mongosh.exe" --ssl --sslCAFile C:\mongo.crt --host 192.168.1.X --port 27017 -u admin -p <YourAdminPassword> --authenticationDatabase admin --sslAllowInvalidCertificates

    NOTE: The IP address and password parameters must reflect the IP of the server hosting MongoDB and the new password entered in the preceding command.
