Two-Factor Login Lock
Type your password as usual. A second screen then asks for the code from your phone, so a leaked password alone gets nobody in.

Mac Security That Asks for Proof
A stolen or shared password should never open your whole life. Lock My Mac adds 2FA login to macOS and gives you a folder lock for private access, all inside one light native app.
Folder Lock for Private Access
Drag in tax papers, client files or photos. Locked folders vanish from Finder and only return after a fresh 2FA check.
Auto-Lock Rules
Pick when your Mac locks itself: after five idle minutes, on sleep or the moment you close the lid. You decide the timing.
Home, Office and Travel Profiles
Each profile carries its own lock timer and folder list. Switch to Travel at the airport and every sensitive folder locks at once.
Menu Bar Control
A small padlock sits next to your clock. Check status at a glance or lock the screen and your folders with one click.
Safe by Design
Secrets stay on your Mac and nothing syncs to a server. Backup codes cover a lost phone so you never lock yourself out.
Terminal installation
Advanced users can install Lock My Mac with a single command.

What Mac Users Say
People who share a desk, travel with a laptop or keep client work on their Mac.
I searched "lock my Mac with 2FA" for months and found nothing that felt native. This one does. The code screen looks like Apple built it.
My kids know my password. They don't have my phone. Problem solved in two minutes flat.
The folder lock is why I stayed. Client contracts sit in a locked folder that simply isn't there until I type my code.
Solid Mac security app. I'd love Apple Watch approval someday, but typing six digits is quick once it becomes habit.
Travel profile is brilliant. One click at the airport and every sensitive folder locks before I pass security.
I tested five tools to password protect a folder on Mac. Lock My Mac was the only free one that didn't feel sketchy.
Lost my phone last week. One backup code later I was back in and paired a new device. Zero panic.
We share one iMac at the studio. Everyone keeps their own locked folders now and nobody opens anything by accident.
Light on memory, quiet in the menu bar and free. Hard to ask for more from a Mac lock app.
