A recall code is a verbal cue used by the Institute to reset synths by incapacitating them to bring them back under their control.


Recall codes are used in the reclamation of B5-92 (Gabriel) from Libertalia and also for the retention of the four escaped synths during the Battle of Bunker Hill. A reset of a synth's cognitive functions is performed by stating: "(synth designation), initialize factory reset. Authorization (recall code)."[1][2][3]

List of known recall codes

Fake recall codes

Deacon mentions that his recall code is "You can't trust everyone,"[11] which is a lie because he is not actually a synth.
