You may have only one ePassi account, at a time, so your previous employer will need to delete your information from your account prior to the launch of a new account.
If there is still some benefit left from the previous job and you have agreed that you have the right to use it, your current employer may create another account by adding one zero to your phone number at the registration stage. In this case, you have two valid accounts that you can sign in and the benefits you can use. To sign up for a new account, sign up with the "00" start number.
If there is no longer left any benefit in your old account, contact your former employer and ask them to remove you from the ePassi system. After that, your current employer can create new credentials for your phone number.
