The administrator of your Clickatell account can invite more users to the account by clicking the profile icon in the top right of the portal and selecting User Management. From here you can add a new user and assign roles to the user.

Clicking the Invite User button sends an email invitation to the user. The email contains a link directing them to the sign-up page where they can set their password and gain access to the portal. What users can access on the portal is determined by the roles you've assigned to them and the permissions and level of access associated with it.

You can edit or remove a user by selecting the user from the user management table.

There are no limits to the number of users you can add to your account.
