At the gate we had a passenger board without permission from gate agent; then we had a non-compliant passenger not wearing a mask. That was mitigated when gate agent came and explained to the elderly passenger that masks must be worn. On taxi out Captain and First Officer were discussing mitigation strategies if that event were to re-occurrence on taxi and failed to run pre-takeoff checklist. Cause - Distraction by pre-flight events with gate agent and non-compliance of the passenger.Remain focused on task at hand. Not replay scenarios until the debrief phase of flight.
Air carrier Captain reported forgetting to do the pre-takeoff checklist due to being distracted by a passenger being boarded without permission and another passenger not complying with face mask policy.
