The Password Fallacy: Why Complexity Isn’t a Substitute for Real Security

2024-05-22

Let’s lay it out plainly: passwords are overrated. Every quarter, some audit or board review triggers a fresh round of password policy tweaking—uppercase! numbers! symbols! change every sixty days!—as if a more convoluted mental gymnastics routine is going to scare off even a passably competent attacker. The problem isn’t that complexity requirements are useless, but that they’re the wrong line of defense for today’s threat models. Singapore’s public sector, no stranger to regulatory diligence and periodic “refresh” cycles, is just as susceptible to this blind spot as any Fortune 500 behemoth or tiny startup clinging to its ISO cert.

What’s rarely discussed outside the closed doors of IT: nearly every major breach in recent history wasn’t the result of a “weak” password, but poor access control, credential reuse, and—let’s be honest—staff clicking on phishing links that not even a 20-character masterpiece could stop. We keep burning hours and sapping goodwill inventing ever-more-arcane password rules, when what really moves the needle are things like enabling MFA everywhere you feasibly can, auditing who can actually access what, and culling old credentials when people move on. These are boring tasks, certainly—the kind that don’t get you congratulatory glances from auditors or headlines in the Straits Times. But they work.

If you’ve ever sat through a password reset spiral—watching teams log endless IT tickets or mutter under their breath about “systems security”—you know these policies create friction that drives bad workarounds. I’ve seen entire teams quietly maintain shared spreadsheets of “complex” passwords, ticking boxes for compliance while gutting any hope of actual secrecy. In the Singapore context, where staff turnover and department reshuffles are routine, orphaned accounts often linger—quiet, forgotten, and perfectly poised for exploitation.

Instead, what if we dropped the myth that “strong” passwords are the core of our digital defense? What if we treated them as the modest barrier they really are—and focused energy on everything else that actually makes a dent in reducing organizational risk? Sure, keep a baseline: no “password123”, and (if your tech supports it) prevent dictionary words. But the adult thing—the CISO thing—is to enforce MFA so a password loss isn’t a single point of failure, ruthlessly prune unused access, and revisit privilege assignments often enough to stay sane.

The next time someone proposes another round of ever-more-complex password policies—safe in the knowledge they’ve “done something”—ask what will actually make adversaries’ lives harder. Odds are it won’t be adding one more special character. True organizational security comes from making smart, continuous improvements to the fundamentals, not clinging to superstition. Choose outcomes over optics. That’s the job.
