How to create strong passwords you can actually use

Most password advice is outdated and counterproductive — the “P@ssw0rd!” style symbol soup is both hard to remember and not as strong as you’d think. Modern guidance is simpler and more effective. Here’s what actually makes a password strong, and how to handle dozens of them without losing your mind.

What actually makes a password strong

Length beats complexity. A long passphrase of several random words is both stronger and easier to remember than a short string of symbols. The two rules that matter most: make each password long, and make each one unique to that account. Length defeats guessing; uniqueness means one breach can’t unlock everything else.

The rules worth following

Keep it simple:

• Aim for length — a passphrase of four or more random words is excellent.
• Never reuse a password across accounts. This is the big one.
• Avoid anything guessable: names, birthdays, “123456”, your pet, your team.
• Change a password promptly if a service tells you it’s been breached.

The system that makes it manageable

Nobody can remember a long, unique password for every account — and you shouldn’t try. Use a password manager: it generates and stores strong, unique passwords for everything, and you only remember one strong master password. It turns “impossible to do properly” into “automatic”.

Add a second lock

Even a perfect password can be phished or breached, so pair your important accounts with two-factor authentication. That way, a stolen password alone still isn’t enough to get in. Strong unique passwords plus 2FA is the combination that actually keeps accounts safe — the foundation of protecting your identity online.
