In one embodiment, a user authentication server may use geo-location tracking to determine whether to present an enhanced identity challenge. A communication interfacemay receive a user login attempt by a user and a current location of the user login attempt. A data storagemay store a user location profile of the user. A processormay execute a comparison of the current location to the user location profile. The communication interfacemay present the user with an enhanced identity challenge before allowing user access based on the comparison.

Protection from unfamiliar login locations

Embodiments are directed to having multiple lockout counters that apply to login requests from different origins. More specifically, one counter is associated with a user's familiar locations, another counter is associated with unfamiliar locations. In another embodiment, hashes of incorrect passwords are recorded so that lockout counters are not incremented multiple times when the same incorrect password is entered repeatedly.

Smart lockout

An integrated authentication service is described which may receive a bundled request from one or more clients. One or more of the described techniques may be utilized to provide, in response to a single bundled request, a token for proof of identity and a certificate for establishing secure communications.
