# Mouse Unlock!—no password, just a secret click pattern > Source: > Published: 2026-05-27 05:31:48+00:00 My 10-year-old laptop has no fingerprint sensor. No Face ID. Just a keyboard. And I was typing a 10+ character password every single time I locked my screen. Lock. Type. Unlock. Lock. Type. Unlock. Repeat 40 times a day. So I thought — my mouse has 3 buttons. What if clicking them in a secret pattern could unlock the screen instead? 2 left clicks → 2 right clicks → 1 left click. Screen unlocked. I'm running Linux (Fedora + KDE Plasma) on a decade-old machine, so I asked Claude Code to build it from scratch. It wrote a Python daemon using evdev that: `/dev/input/` (works even on Wayland lock screen)`loginctl` `loginctl unlock-sessions` The whole thing is ~150 lines of Python. No PAM hacks. No special hardware. Is it secure? Absolutely not — but neither is a laptop old enough to be in 5th grade. 😅 Old laptop. No biometrics. Zero excuses now. 🖱
