Adding the accounts packages

To start using a login system, we need to add the accounts-ui and accounts-password packages to our app, as follows:

1. To do so, we open up the terminal, navigate to our my-meteor-blog folder, and type the following command:

   $ meteor add accounts-ui accounts-password
   

2. After we have successfully added the packages, we can run our app again using the meteor command.

3. As we want to prevent the creation of additional user accounts by our visitors, we need to disallow this functionality in our accounts package, config. First, we need to open up our my-meteor-blog/main.js file, which we created in the previous chapter, and remove all of the code, as we won't need the session examples anymore.

4. Then add the following lines of code to this file, but make sure you don't use if(Meteor.isClient), as we want to execute the code on both the client and the server this time:

   Accounts.config({
       forbidClientAccountCreation: true
   });

   This will forbid any call of Accounts.createUser(...
