MULTIPLE DEVICE COLLABORATION AUTHENTICATION

An approach to multi-device collaboration authentication may be provided. The approach may include generating a password in response to a user requesting access to a service or application on a primary device. The approach may include dynamically determining whether secondary devices are located physically near a primary device. The generated password may be segmented into two or more parts, based on the number of secondary devices the physically located near the primary device. A password segment can be sent to the primary device and another segment of the password can be sent to the secondary device determined to be physically near the primary device. The approach can include receiving the password segments in prescribed manner to provide authentication and grant access to the requested application or service.
