How to add admin users in Magento 1.x

Overview

Should you need give another individual, such as a developer, temporary access to your Magento store, use the below procedure to create an additional admin account. This is far preferable to divulging your personal credentials, and also allows you to easily revoke the account when no longer needed.

The procedure involves two main steps: adding the user role, then adding the user.

1: Add user role

If you wish to grant complete admin access to the user, you may skip to 2: Add user instead of creating a specific role. This will, however, involve granting the new user complete admin access and therefore access to all of your store's most critical areas. Use care when assigning the Administrator role. 

1. Log in to your Magento Admin panel.
   
   
2. From the Admin Panel, select System > Permissions > Roles.
   
   
   
3. Click Add New Role.
   
   
   
4. In the Add New Role section, enter the desired name in the Role Name field and your current password in the Current Admin Password field.
   
   
   
5. In the Role Information section on the left, select Role Resources. 

   

6. Attention: In this step, you will choose which permissions to assign to the new role. If you are unsure, consult with your developer. As always, take care when assigning permissions, as many grant secure access to critical areas of your store.
   
   From the Resource Access drop-down list, select Custom if not already selected. Assign permissions as desired.
   
   
   
7. Click Save Role.
   

2: Add user 

1. From the Admin Panel, select System > Permissions > Roles.
   
   
2. Click Add New User.
   

3. In the Account Information section, fill all fields, then from the This account is drop-down list, select Active if not already selected. 
   

4. Attention: In this step if you are assigning the default Administrators role instead of a custom role, be aware you are granting this user complete access to all of your store's most critical areas. Use care when assigning this role.
   
   On the left, click UserRole, then select the check box corresponding to the role you created in the "1: Add user role" section. If you want to grant complete admin access, select the Administrators check box. 
   
   
   
   

5. Click Save User.
   
   

6. Test the newly created login credentials. If they function, this procedure is complete.
