🔒️ Security by subtraction


“Complexity is the enemy of security.”

By now, you’ve probably noticed a pattern in these early 2026 emails.

Nothing dramatic. Nothing scary. Just small, calm steps that quietly reduce risk.

This week is about one of the most overlooked security wins there is:

Removing things instead of adding them

Most people think better security means: - more tools - more settings - more apps - more effort

In reality, it usually means less.


The problem nobody sees

Over the years, we all accumulate digital clutter:

  • accounts we signed up for once
  • apps we don’t remember installing
  • services we “just tried”
  • logins tied to old email addresses
  • permissions we granted years ago and forgot about

Each one is a tiny, forgotten door.

On their own, they don’t feel dangerous. Together, they quietly increase your risk – and your stress.


A simple exercise (no tools required)

Here’s a low-effort way to start:

  1. Search your email inbox for:
    • “Welcome”
    • “Thanks for signing up”
    • “Verify your email”
  2. Scroll back a year or two.
  3. Notice how many services you’ve forgotten entirely.

You don’t need to fix everything today. Just notice.

Awareness alone changes behaviour.


What to remove first

If you feel like taking one small action this week, focus on:

  • Accounts you no longer use
  • Apps you haven’t opened in months
  • Services that don’t need access to your email or profile anymore

If deleting feels risky, start by: - changing the password - removing saved payment methods - revoking third-party access

Less surface area means fewer surprises later.


Why this matters more than people realise

Most real-world breaches don’t come from brand-new services. They come from: - old accounts - reused credentials - forgotten permissions - systems nobody is watching anymore

Security improves fastest when you reduce what needs protecting.


A quiet goal for this week

Don’t aim for “perfect.” Aim for simpler.

One fewer account. One fewer app. One fewer place your data lives.

That’s real progress.

Next week, we’ll talk about backups – not as a technical chore, but as peace of mind.

Stay safe out there,

"The most dangerous apps aren't the ones you download. They're the ones you forgot about." The family tablet had been getting worse for weeks. Not "a bit slow" worse. Painful. Every tap took seconds to register. Scrolling stuttered like a slideshow. Apps crashed mid-use. And the ads - they were relentless. Full-screen popups appearing out of nowhere, covering whatever you were doing, sometimes impossible to close without accidentally tapping through to whatever rubbish they were pushing. At...

"Just because it can connect to the internet doesn't mean it should." My dishwasher died last week. Mid-cycle, no warning - just a puddle on the kitchen floor and a error code nobody could decipher without Googling. No drama. Appliances break. You clean up, you go shopping, you move on. I figured I'd have a new one ordered within an hour. Instead, I spent an entire evening down a rabbit hole that genuinely rattled me. I started where most people start - filtering by price, brand, and energy...

“Automation doesn’t remove responsibility. It concentrates it.” Ben decided to let the AI “handle things” overnight. Inbox triage. Calendar cleanup. Draft a few polite replies. Nothing risky. He even joked that it felt like having a junior assistant working the night shift while he slept. By morning, the inbox was spotless. A little too spotless. Threads had been archived he didn’t remember reading. A meeting had been rescheduled. A service he vaguely recognised was suddenly on a more...
