Creating New UsersFor stores with multiple merchants, there is an option to add administers, with their own access username and password. Different Roles can be created for different types of users.
Unlocking User AccountsFor the security of your site, by default a user is given 6 attempts at logging in. If the user fails on the 6th attempt then his/her log in name will be locked.
Sharing Access to Your Magento AccountYour Magento account contains information that can be useful to trusted employees and service providers who help manage your site. As the primary account holder, you have the authority to grant other Magento account holders limited access to your account.
Creating Custom RolesTo give someone restricted access, the first step is to create a role with the appropriate level of permissions. After the role is created, you will add the new user, set up the login credentials, and assign the role to the user account.
