How to add a new user

If you would like to give someone access to the back-end (dashboard) of your website without sharing your login details, you may add them as a new user. To add a new user, use the Add a New User link in your dashboard under the ‘Settings’ heading:
When creating a new user, you are required to give them a Username, Email and Password:
You may optionally enter their First and Last Names and a link to their Website:
Decide if you want the new user to receive an email informing them of their new account (if you leave this unchecked, you will need to get in touch with them yourself to let them know their login details) and select a Role for them (explained at the end of this article). Finally, click the Add New User button:
The user will now be created and they can login from your website’s login page.
