Yuko, did you see the news? A man used his fingerprint and repeatedly unlocked his neighbor’s smart door lock.

I saw it. It shocked me. Aren’t fingerprints supposed to be very secure? How could it open the wrong door?

Maybe the lock had a problem. Some say the fingerprints were too similar, and others say someone else’s fingerprint might have been recorded during setup.

I see. I used to think smart locks were the safest. Now I’m a bit worried.

Actually, most locks are still reliable. You just need to remember to change the default password and avoid using factory settings.

Mm, and check the door-opening records, right? That way you can see who opened the door.

Yes. Many locks keep logs. If something seems wrong, replace the lock immediately and contact the seller.

Hearing that makes me feel better. Safety really is the most important.
