You can think of Entrust as an international counterpart of itsme. Both systems are used to prevent identity fraud by means of identity verification.
Itsme is for users with Belgian identity documents, whereas anyone can use Entrust. To verify your identity with Entrust, you need your national identity card or passport. The verification process involves scanning this document and comparing it to your face in a video recording lasting a few seconds. Only the owner of the identity card or passport can be verified in this way.
