Normally, access to Atlas is automatically discontinued after separation. However, it is allowed to have eService only access after the separation for three months. This is typically granted to allow staff to claim for their Education Grant.
You would need to ask your Supervisor to kindly ask your Argus focal point to delete your current Atlas user profile and then ask firstname.lastname@example.org for 3 months access to eServices.
Please note that UNFPA does not allow for eServices access after separation date.
