Authentication using dynamic verbal questions based on social and geospatial history

An approach is provided for authenticating a user. Geolocations are collected during a first time period and social media interactions are collected during a second time period. Historical data is polled which indicates (1) geolocations whose timestamps indicate locations of a person authorized to access the device within the first time period and (2) social media interactions whose timestamps indicate interactions of the person within the second time period. A question is generated to be relevant to a social media interaction and/or a geolocation included in the historical data. The voice of the user who provided an answer to the question is verified as matching a voice of the person authorized to access the device. The answer is determined to be correct. Based on the matching voices and the answer being correct, the user is authenticated and access to the device by the user is granted.
