My neighbors have been stealing my wifi over and over again. They've even taken my password for it. So, after weeks of telling them not to take it, I had enough. So I started working on code. Whenever a new device tries to log in, they will grant consent for a security check. That security check will lock the device until a 40-character code is entered. Its going to be a fun evening when my neighbors try to watch HBO. EDIT: They're so mad. So very, very mad. They threatened to sue until I pointed out that this was just a security measure I had installed. So I offered to unlock their device, which they accepted. I don't think I'm going to need to do that again.
