An application requires a second factor authentication, but I do not have access to it anymore

If you do not have access to your configured second factor(s) anymore, you will have to erase all registered phone numbers and mobile devices registered with your EU Login account.

This action does not require you to use a second factor and will remove all phone numbers and devices linked to your account, you will then be able add new ones.
