Pairing method, in which a gateway serves as a wireless access point to at least one first secure wireless local area network and to a second secure wireless local area network, the gateway interconnecting the second secure wireless local area network and a wide area network such that each communication device paired with the second secure wireless local area network is able to access services offered via the wide area network, a provisioning server being connected to the wide area network, the method being implemented by the gateway and comprising the following steps: - detecting a first pairing attempt by a communication device to pair with a said first secure wireless local area network, in which the communication device is identified and provides first authentication data; - checking that the first authentication data correspond to authentication data expected by the gateway in relation to said first secure wireless local area network; - in the event of a positive check, confirming the first pairing with said first secure wireless local area network and transmitting second authentication data and a network identifier of the second secure wireless local area network to said communication device via said first secure wireless local area network; - detecting a second pairing attempt by the communication device to pair with the second secure wireless local area network, in which the communication device provides different authentication data; - checking that said different authentication data correspond to said second authentication data; and - in the event of a positive check, confirming the second pairing with the second secure wireless local area network, so as to allow said communication device to access said services offered via the wide area network, the gateway not allowing the services offered via the wide area network to be accessed via the first secure wireless local area network, the method furthermore comprising the following step in order to confirm the first pairing with said first secure wireless local area network: - checking (401, 405) with the provisioning server that said communication device is associated with the same user as the gateway, and, in order to check that said communication device is associated with the same user as the gateway and in order to check that the first authentication data correspond to the expected authentication data, the gateway, before the first pairing attempt by the communication device to pair with a said first secure wireless local area network is able to be detected thereby, receives from the provisioning server a descriptor including, for each communication device from among a set of communication devices likely to pair with the second secure wireless local area network: - a communication device identifier, - a network identifier, and - expected authentication data in relation to the first secure wireless local area network; and the method furthermore comprising, after receiving said descriptor and before said first pairing attempt is able to be detected by the gateway, the gateway creates a said first secure wireless local area network for each communication device from among said set of communication devices likely to pair with the second secure wireless local area network, by assigning said first secure wireless local area network the network identifier of the descriptor of the corresponding communication device. - detecting a first pairing attempt by a communication device to pair with a said first secure wireless local area network, in which the communication device is identified and provides first authentication data; - checking that the first authentication data correspond to authentication data expected by the gateway in relation to said first secure wireless local area network; - in the event of a positive check, confirming the first pairing with said first secure wireless local area network and transmitting second authentication data and a network identifier of the second secure wireless local area network to said communication device via said first secure wireless local area network; - detecting a second pairing attempt by the communication device to pair with the second secure wireless local area network, in which the communication device provides different authentication data; - checking that said different authentication data correspond to said second authentication data; and - in the event of a positive check, confirming the second pairing with the second secure wireless local area network, so as to allow said communication device to access said services offered via the wide area network, - checking (401, 405) with the provisioning server that said communication device is associated with the same user as the gateway, - a communication device identifier, - a network identifier, and - expected authentication data in relation to the first secure wireless local area network;
