Methods and systems for authenticating a user requesting to access one or more resources via a device are described herein. Authentication may be based on or otherwise rely on a plurality of devices. For example, aspects described herein are directed towards a system and method for receiving a request from a user to access one or more resources via a first device. In response to receiving the request to access the one or more resources, the first device may send, e.g., to a second device, a request for user input of a credential at the second device. The first device may receive a credential from the second device, and the first device may authenticate the user based on the received credential. Additionally or alternatively, the second device may authenticate the user based on an input of a user credential, and the second device may send an indication of a successful authentication to the first device.
