Dynamic passcodes in association with a wireless access point

A system comprising:

• a processor of an access point;
• a memory coupled to the processor, the memory including instructions executable by the processor to perform operations, the operations including:
• during a usage period of a first passcode that enables access to a network and for an initial access request during the usage period for each user device that sends a valid access request to access the network based on the first passcode during the usage period, adding an identifier of the user device to a device list for the first passcode;
• after expiration of the first passcode, receiving, from a first device, a first access request to access a local area network, the first access request encrypted based on the first passcode;
• in response to the first access request and before expiration of a usage time of the device list for the first passcode, determining whether an identifier of the first device is included in the device list for the first passcode;
• and
• in response to the determining indicating that the identifier of the first device is included in the device list for the first passcode:
• generating data representing a second passcode by encrypting the second passcode based on the first passcode;
• sending the data representing the second passcode to the first device;
• and
• removing, at the access point, the identifier for the first device from the device list for the first passcode.

A processor-readable storage device storing instructions that, when executed by a processor of an access point, cause the processor to perform operations, the operations comprising:

• during a usage period of a first passcode that enables access to a network and for an initial access request during the usage period for each user device that sends a valid access request to access the network based on the first passcode during the usage period, adding an identifier of the user device to a device list for the first passcode;
• after expiration of the first passcode, receiving a first access request from a first device, the first access request encrypted based on the first passcode;
• in response to the first access request and before expiration of a usage time of the device list for the first passcode, determining whether that an identifier of the first device is included in the device list for the first passcode;
• and
• in response to the determining indicating that the identifier of the first device is included in the device list for the first passcode:
• generating data representing a second passcode by encrypting the second passcode based on the first passcode;
• sending the data representing the second passcode to the first device;
• and
• removing, at the access point, the identifier for the first device from the device list for the first passcode.
