When you add an employee to your TalentHR domain, an automatic email invite is sent to them. It contains a link that allows the employee to create their first password and login.
In case the link in the invite email has expired, your employee can reset their password by navigating to your TalentHR domain URL and following the steps here.
This way, the employee can create a new password and gain access to their account.
Alternatively, you can simply resend the initial Invitation link to any employee of your choice.
