A method for authenticating a mobile identity (ID) is provided. The mobile ID is provided on an end device of a user. Personal information about the user is first brought into anonymized form via a one-way function known to the end device of the user and to a first entity and transmitted with a single mobile ID certificate to the first entity. A communication exchange between the end device of the user and the first entity is henceforth identified by this mobile ID certificate. At a later point in time, the user is provided a permission option to transmit the personal information in non-anonymized form to the first entity. The first entity uses the then transmitted non-anonymized personal information to check its anonymized form.
