Reuse is the real password problem

Password advice fixated for years on complexity — a capital letter, a number, a symbol, changed every ninety days. Most of that advice has aged badly. The rules produced passwords that were hard for humans to remember and easy for computers to guess, and forced rotation just trained people to append a number to the same base word. Meanwhile the actual problem went largely unaddressed: reuse.

Why reuse is the danger

When a website you use is breached — and they are breached constantly — the attacker walks away with a list of email addresses and passwords. The first thing they do is try those same combinations everywhere else: your email, your bank, your business systems. If you reused the password, the breach at some hobby forum you forgot about becomes a breach of your company. The technique has a name, credential stuffing, and it is automated, cheap and relentless.

The fix is boring and effective

Two things solve most of this. First, a unique password for every account, so a breach in one place stays in one place. No human can remember dozens of unique strong passwords, which is exactly what a password manager is for: it generates and stores them, and you remember one. Second, multi-factor authentication on anything that matters, so a stolen password alone is not enough to get in.

For a business

A shared team password manager does more than improve hygiene. It gives you a way to grant access without emailing passwords around, to revoke it instantly when someone leaves, and to see what credentials exist in the first place. That visibility is often the most valuable part — you cannot secure logins you did not know your team had created.

The uncomfortable truth is that most people are one reused password away from a bad week. The tools to fix it are cheap, well understood, and long overdue in most organizations.
