Aspects of the present disclosure provide systems and methods for access control using multi-factor validation. In an example, an access control system is designed to be used in conjunction with a first recognition system, such as facial recognition system, a gait recognition system, or audio recognition system, that uses a confidence level to determine whether individuals are authorized to access a restricted area. When the first recognition system is unable to confidently identify the individual, a second recognition system, such as a mobile device system or access card system, may be used to provide second factor verification. Further, stored recognition data may be updated to include information gathered by the first recognition system in response to use of the second factor verification.
