Abstract
This disclosure describes techniques for using an anchored endpoint to enhance MFA authentication of a client device. A method performed at least in part by a security service includes authenticating of a client device connecting to a secure resource. The method also includes determining a first Wi-Fi fingerprint of the client device, determining that the client device is within a threshold proximity to an anchor device, and determining a second Wi-Fi fingerprint of the anchor device. The method also includes detecting a change to the first Wi-Fi fingerprint of the client device and determining that the second Wi-Fi fingerprint of the anchor device has not changed. The method also includes determining whether the client device is within the threshold proximity of the anchor device, if it is, access to the secured resource continues to be allowed, if it is not, a reauthentication of the client device is triggered.
