System and method for authenticating multiple devices with a same credential

A method for providing a network service, the method being implemented by one or more processors and comprising:

• identifying a device used to communicate a set of credentials;
• determining that the identified device is not a first-in-time device used to access the network service using the set of credentials;
• making a determination as to whether a condition is satisfied for authenticating the identified device a follow on device to the first-in-time device, the condition including the identified device accessing the network service using the set of credentials within a defined time period following the first-in-time device accessing the network service using the set of credentials;
• and
• permitting access to the network service for the identified device based on the set of user credentials only if the condition is satisfied.

A non-transitory computer-readable medium that stores instructions that, when executed by one or more processors, causes the one or more processors to perform operations that include:

• identifying a device used to communicate a set of credentials;
• determining that the identified device is not a first-in-time device used to access a network service using the set of credentials;
• determining whether a condition is satisfied for authenticating the device as a follow on identified device to the first-in-time device, the condition including the identified device accessing the network service using the set of credentials within a defined time period following the first-in-time device accessing the network service using the set of credentials;
• if the condition is satisfied, permit access to the network service for the identified device based on the set of user credentials;
• else deny access to the network service.

A system comprising:

• means for identifying a device used to communicate a set of credentials;
• means for determining that the identified device is not a first-in-time device used to access a network service using the set of credentials;
• means for making a determination as to whether a condition is satisfied for authenticating the identified device as a follow on device to the first-in-time device, the condition including the identified device accessing the network service using the set of credentials within a defined time period following the first-in-time device accessing the network service using the set of credentials;
• means for permitting access to the network service for the identified device based on the set of user credentials only if the condition is satisfied.
