Yes, it is possible. If you give a card restored by the same employer, will be automatically assigned to you to the Edenred mobile application.
If you have changed employers and have another card from a new employer, you need to create a new personal online account in the My Edenred customer zone with a new LOGIN NAME. You'll need an email address that you haven't used in any online Edenred account before.
Then log in to the MyEdenred mobile application by new credentials that you used to create a new one personal account in the My Edenred customer zone.
If you want to use the same e-mail address, you need to change the e-mail address in the previous online account to another one, and then it will be possible to use the original e-mail to create a new account.
