Claim:
A method for authorizing access of a user to a first computing device, the method comprising the steps of: capturing, by a second computing device of the user, a symbol from the first computing device; decoding, by the second computing device of the user, the symbol into a challenge; generating, by the second computing device of the user, a request from the challenge; providing, by the second computing device of the user, the request to a server for processing by the server to generate an access code to authorize and allow access to the first computing device by the user, wherein the challenge obtained from decoding the symbol comprises an identifier of the first computing device, an address of the server to which the request is provided and a function differentiating challenges formed at different times; the server forming a decision to allow the user access to the first computing device based on information contained in the request received from the second computing device of the user; the server forming the access code, if the user of the second computing device is allowed access to the first computing device; and the server sending the access code to the second computing device of the user.
