Yes, here is how you can do that.
Click SETTINGS at the top right of the navigation menu
Click Team Settings
Enter the new user's email
Click INVITE TEAM MEMBER
Your new user should receive an email which contains a link to Create Account
Once clicked on the link, the new user should enter first name, last name, email, and password, tick on terms & conditions checkbox and reCAPTCHA verification, then click REGISTER
The new user is now able to login, please keep in mind that all users are able to see your bookings, contacts
As a best practice, you should always have 2 or above Primary Users in your company's account
