Beschreibung
Zusammenfassung:	The invention relates to an authentication method (100) using a first authentication factor and a second, biometric authentication factor, the authentication device (DA) comprising a server (S) and an authentication terminal (TA), comprising a device for acquiring biometric user information (IBU), the user terminal (TU) storing a reference biometric template (GBR) of the user and a user identifier (IDU), the method (100) comprising the following asynchronous steps: transmission (101) of the user identifier (IDU) to the server (S) when a first communication condition dependent on a position of the user terminal (TU) is satisfied, receipt (102) by the user terminal of a challenge (CHA) from the sever (S), signing (103) of the challenge (CHA) to produce a signed challenge (CHS), encryption (104) of the reference biometric template (GBR), and transmission (105) of the signed challenge (CHS), the encrypted reference biometric template (CGBR) and the user identifier (IDU) to the at least one authentication terminal (TA).
