How to manage accounts and account settings in Drupal
To edit the user accounts of individual users and to add new users, log in to the admin panel of your Drupal and click on the People tab in the top navigation bar. You'll see a table with all the registered users. To activate/block users, to cancel their accounts, or to assign a user(s) to a user role, mark the checkbox in front of the particular user(s), then select the action from the Update options drop-down menu and click on the Update button. To edit the account of a user simply click on the edit button for that user. You can change the username, password, email, etc.
You can also add new users. To do this click on the Add user button that's above the top left corner of the table with the registered users, and configure the settings (they are the same as on the edit account page).
You can also change the global account settings. These settings apply to all accounts. To do this click on the Configuration tab of the Drupal admin panel, and on the page that opens click on Account settings. On the page that opens there are several sections: Anonymous Users, Administrator Role, Registration and Cancellation, Personalization, E-mails.
From the Anonymous Users section you can change the name used to refer to unregistered users. The Administrator Role section allows you to set the default admin user role. From the Registration and Cancellation section you can change the way in which new users can be registered and also what happens with an account and its content when the account canceled. By default, visitors/anonymous users are allowed to registered, but they have to be approved by an administrator; email verification is also performed. If you want to, you can choose some of the other available options. When an account is canceled, by default it's disabled and its content (e.g. comments, articles, etc.) is kept on the frontend. In this case, there are also some other available options (e.g. delete the account and its content, etc.).
From the Personalization section you can enable/disable signatures and enable/disable user pictures (avatars). By default, signatures are disabled and avatars are enabled. With pictures enabled there are some more options (allowed size, dimensions, etc. ). From the E-mails section you can edit the subject and content of email templates. These templates are sent automatically to users for important reasons concerning their accounts (e.g. account activation, account approval, etc.). When you're done with the global account settings click on the Save configuration button.
At the top right corner of the Account settings page there are two sub-tabs that you can use to add and manage fields that appear on the user account page. These sub-tabs are Manage Fields and Manage Display. You can add new fields and edit the settings of existing fields. These are the fields that appear on the page on which you can edit the account of individual users, not the page displaying the global account settings.
