Devices, systems and methods are disclosed which relate to restricting access to a secure resource by requiring a multimodal input sequence as a passkey to access the secure resource. Certain techniques allow a user to provide simultaneous input through a plurality of input sensors on a handheld device to create a multimodal input sequence, which is used as a unique passkey required to access secure resources. Combinations of input sensors are used to complete the multimodal input sequence. Among the available input sensors are an accelerometer, a touch screen, a camera, a proximity sensor, a position sensor, etc. The secure resource can be data or materials. |
