I remember reading a short story about a girl with an interesting superpower. She can go anywhere (e.g. any secure facility) without causing suspicion - the people around always take it for granted that she belongs there.
I tried a few Google searches to find the story, but I've had absolutely no results. Does anyone know what this is?
It is the short story "Access" by Andy Weir, the author of the comic Casey and Andy and the novel The Martian. You can read the full text online on Andy Weir's creative writings website.
The girl describes her power like this:
“As far as I can tell, everywhere I go, everyone thinks I’m supposed to be there.”
Could it be Imp from the web serial Worm?
From the cast page:
Her power renders her unnoticeable, to the point that people she attacks don’t remember she attacked them.
I think the other two have it covered, but if it were online fiction, it's also possible that it's Dorothy Maxwell, a side character in "I Looked into the Abyss, and it Winked", a Whateley Academy story. She has a powerful uncontrolled ESP talent that causes everyone to forget she was there. She can interact with people, but they retain no memory of the encounter.
