Abstract: A method for enabling secure transactions without the physical support of a security identifier and, in particular, without a token, consisting in recording on a first computer device B a unique digital identifier IDi associated with a unique user Ui, the profile IDi being associated with at least one service identifier IDsi associated with a service Si registered on a second computer device S which is different from the first computer device B, the service Si being accessible by the user Ui, and, during a transaction, acquiring the digital identifier IDi of a user Ui, transmitting it to the first computer device B for comparison with the registered ID identifiers and searching for and activating on the computer device S, at least one service associated with the identifier of the user Ui.
