Mongodb Set Username And Password

Mongodb Set Username And Password – Configuring MongoDB as a custom database can simplify your user migration process or even add an OAuth and OpenID Connect layer on top of your existing user database. Whatever your reason, let’s take a step-by-step look at the process of connecting to MongoDB.

After logging in, go to the Database Connections page and click the Create DB Connection button.

Give this database configuration a meaningful name, click the Create button, and then go to the Custom Database tab.

On this screen you can enable the Use my own database option and define the JavaScript to run when the following events are triggered:

Each of these scripts will have a Templates drop-down menu above the code editor, and MongoDB is one of the out-of-the-box options. You will come back to this later.

But before you do that, set up your MongoDB instance. Assuming you already have an account at, go to your dashboard and navigate to the Projects tab. Then create a new project and a new cluster in this project. Free, shared sets with default settings are sufficient for our purposes, but if their features better suit your needs, consider one of the paid options.

This guide should also work fine if you’re using an existing database, but you may need to adapt some of the upcoming instructions to suit your particular circumstances.

After the cluster is created, which can take up to three minutes, you need some connection details to use it in control panel scripts.

Click the Connect button and configure the IP addresses that can connect to your cluster. If you look back at the UI, you’ll see a list of IP addresses under the code editors of one of your scripts. Add them using the “Add another IP address” button in MongoDB.

Next you need to define a user who is allowed to connect to the system. Choose a username and a sufficiently strong password and continue.

Finally choose a connection method. The scripts you configure fall under the Connect Your App scenario and clicking on it will bring up the connection string that you need to use in your scripts.

Copy the connection string from MongoDB and return to the interface. Select this option to edit the login script and select MongoDB from the Templates drop-down menu.

Replace the entire connection string with the value you copied from MongoDB and you’ll see something that looks like this:

But there is a solution for that. At the bottom of the script editor you will see a Settings section where you can save all script data via environment variables. This is a much more secure way of storing the password.

You can then copy the code snippet from the new entry and use it in your connection string instead:

Next you need to create a database and a collection in MongoDB. Switch back to the MongoDB interface, close the connection information dialog and click the Collections button.

That’s it for this step! The database is ready and all you have to do is complete the custom database configuration.

Go back to the UI and you should see the Login Script Editor. The script already links to:

Collect. If you used different names in the previous step, make sure to update the code in all scripts on lines 8 through 10:

Before proceeding, copy line 4, which starts the client with the correct connection string, to your clipboard.

To configure other scripts, iterate through each one, choose MongoDB from the Templates drop-down menu, and replace the client initialization line with the line you copied from the login script.

No flags, so later setting doesn’t work. To fix this, go back to the create script and find the line that defines its value.

Now when someone creates a new account, it will be created with the new user object in MongoDB.

The second change concerns the delete script. In line 11 you can see the line that tells MongoDB to delete the user:

Clicking the Save button above the script editor will save any changes made to all scripts. So strike and done!

You can now test any of these scripts with the Try button. If you’re starting with a new database, try the create script first and go from there.

If you are using an existing database, you can try to log in using an existing user’s credentials. For authentication issues, ensure that the login script uses the same hash mechanism as the code that created those users.

User Manager, along with Role Manager, simplifies MongoDB user management tasks like creating users and assigning roles. Try both features today.

With Studio 3T 2018.4 it is now possible to view the JSON code behind the user creation by clicking View Code.

Find the role by typing the text or selecting from the list. Built-in roles are denoted with a yellow icon and custom roles are denoted with a green icon.

If you want your new user to have access to other databases, you can also click the combo box above to choose from roles in other databases of your MongoDB instance.

For our example we will make our new user the administrator of the database and also give him read and write access by selecting roles.

In MongoDB, users are defined for specific databases. Each user is then assigned a list of roles, which in turn define the user’s permissions.

Not surprisingly, MongoDB’s API therefore makes it easy to grant a user a list of roles via the grantRolesToUser method:

However, MongoDB’s Roles API ( doesn’t directly cover another common use case (possibly newly created) that you want to assign away. ) Add role or multiple roles at once to a list of users.

Let’s consider the following example. Let’s say you create a new role “rwAdmin” in the database “test” that makes users dbAdmins in that database and allows them to read and write at the same time. Now you want to assign this new role and the existing userAdmin role to a group of users.

Connect to your MongoDB server as a user with sufficient privileges to assign users to roles, select the database where your users are defined, and click the Users icon on the toolbar to bring up the User Management tab ‘ for this database.

You will now see a list of all your users in the selected database. Select all the users you want to assign these roles to and click the “Assign Roles…” button.

Now, from the list of available roles, select the ones you want to assign to your selected user list and click Grant.

After you’ve completed the role assignment, learn more about how to set up user authentication or learn more about the complementary role manager feature.
