Abstract: An authentication system to authenticate at least one application accessible by a user via a computer for which access is controlled by an authentication datum includes a main mobile device and a main token in which the authentication datum is recorded. The main mobile device is configured to recover the authentication datum of the main token using a pairing key that is segmented into a plurality of segments. A first segment is recorded on the main mobile device and at least one additional segment is recorded on a secondary mobile device and/or a secondary token. The main mobile device is configured to recover the additional segment or segments in order to reconstitute the pairing key and to present the reconstituted pairing key to the main token.
