Doctor Lesko's password recording is a holotape in Fallout 3.
Location
It can be found in the recently built shack in Grayditch, where it was left by its author Doctor Lesko. It can be used to access his terminal.
Transcript
This could be the fifth time I've forgotten the code to my desktop terminal. I really must learn to be more organized.
The password for my terminal is "formicidae." How hard could that be for me to remember?
Note to self: destroy this holotape as soon as move to new lab is complete.
