Mass. Pike Tunnel password

 is a holodisk in Fallout 4.

Characteristics
The holodisk is mostly useless; it is used to access a terminal in the Mass Pike tunnel that opens a maglocked door, but the area behind the door can be accessed through a nearby hole in the wall.

Location

 * The holotape is located beside the skeletal remains of Detective Francis Perry in the southern portion, off the main tunnel of the Mass Pike Tunnel.
