Blue2Factor

Frictionless, secure multi-factor authentication. Blue2Factor authenticates users without any user interaction by verifying that the device that is being used to sign into a domain is in close proximity to one of the user's other devices. For example, if a person is signing into a domain on their computer, Blue2Factor makes sure that their phone, tablet, or smartwatch is nearby. Authentication is nearly instantaneous so users can be validated each time a domain is visited.
