As the Super Admin/Admin of your Site24x7 account, you will be able to invite and add a user to be part of your Site24x7 account. When the primary Site24x7 account holder adds a sub-user, a Site24x7 account will be automatically created for that email address. The newly created sub-user account will receive two emails from Site24x7 immediately after the account creation.
Email containing temporary password - Sub-user can login and change the password under Admin > My Account > Change Password
Account confirmation email - Sub-user should verify the newly created sub-user account by clicking the verification link sent via email. No alerts or configuration emails will be sent to the sub-user, until the email address is verified.
