Two-Factor Authentication for a Microwave: When Security Goes Too Far

I wanted to reheat a cup of tea. That's the whole story I set out to tell you. Instead, my microwave — a device whose entire job is "make thing hot" — asked me to open an app, sign in, and confirm a six-digit code sent to a phone I'd left in the other room. By the time I'd done all that, the tea had gone cold enough that reheating it felt like starting from scratch on a much sadder cup of tea.

Smart doesn't always mean better

Somewhere along the way, "smart" became the default setting for every appliance, whether it needed it or not. A smart fridge can tell you the weather. A smart kettle can be controlled from a different postcode. None of this was on anyone's list of actual problems. The dial worked. The dial always worked.

Why the login screens keep showing up

It's rarely about your safety and usually about data — the more an appliance knows about when you're home, what you eat, and how you use it, the more useful that information is to whoever made it. A login screen is how they make sure that data has your name attached to it. Reasonable, in theory. Deeply annoying, in the specific case of trying to heat up a two-minute noodle before a meeting.

How to keep your kitchen simple

• Before buying an appliance, check whether the "smart" features are optional or forced — some let you skip setup and use physical buttons entirely.
• If a basic model without an app still exists, it usually costs less and breaks less.
• Where you must connect a device, use a separate, disposable-feeling email address rather than your main one — fewer notifications, less to untangle later.

I'm not against progress. I'm against a login prompt standing between me and a hot beverage. Somewhere there's a very clever engineer who solved a problem nobody had, and somewhere else there's a cup of tea going cold. That's the whole review.
