Create an account for each team member, assign their department and issue a temporary password. Members can change their own password later.
The temporary password is shown once. The member must replace it at first sign-in.
Update the member's name, department or access.
This signs the member out everywhere and forces a password change at next sign-in.
Copy this password now and share it with the member through your usual secure channel. It is not stored anywhere in readable form and will not be shown again.
