What kind of an identity verification is to just ask people and take them at their word?
Guard: "What's your name?"
MC: "Alma Fellows... I mean, all my fellows are waiting for me in some other town, far away from here. My name is Shmalma Shmellows. I'm totally not some dangerous OP wizard. No, sir, not me at all."
Guard: "... Okay, that checks out. Have a nice day, sir."
