How to Generate a Password That Actually Holds Up

When most people create a password, they start with something familiar — a name, a date, a word — and then modify it. Add a capital letter. Throw a number on the end. Maybe swap an "o" for a zero.

It feels creative. It isn't. Those patterns are so predictable that attackers build them directly into the tools they use to crack passwords. "Password1!" fails in seconds. So does "M@rch2019" and "fluffy#1".

The only password that's genuinely hard to crack is one with no pattern at all — one that was never invented, just generated. If a site asked you to create a passphrase instead of a password and you're not sure what the difference is, the passphrase guide explains it — they're related but serve different situations.

Two things determine how hard a password is to crack: length and randomness.

Length matters more than most people realize. Every character you add multiplies the number of possible combinations an attacker has to try. A 12-character password isn't twice as hard to crack as a 6-character one — it's astronomically harder.

Randomness matters because patterns are weaknesses. If your password is based on anything meaningful to you — or follows any rule a human would naturally apply — it's less random than it looks. True randomness means no word, no date, no substitution, no pattern. Just characters chosen without any logic a person would recognize.

A generator produces that. Your brain can't.

Here's the real-world problem with strong passwords: the site you're creating one for may not accept it.

Some sites cap passwords at 10 or 12 characters. Some ban symbols entirely. Some allow only letters and numbers. Some restrict which symbols are valid. These limitations are frustrating and often reflect outdated security thinking on the part of the site — but they're real constraints you have to work around.

A fixed generator that always produces the same format won't help you here. If a site requires exactly 10 characters, alphanumeric only, you need to be able to generate exactly that — without falling back to something you invented yourself.

This is why a configurable generator matters. You want to match the strongest password the site will actually accept, not settle for a weak one because the tool couldn't adapt.

The ZTDev Password Generator runs entirely in your browser. Nothing is sent anywhere — not to a server, not to any third party. The password is generated locally using your device's cryptographically secure random number generator, which is the same randomness source your operating system uses for security-critical operations.

What makes it practical for real use:

Adjustable length. Set it to whatever the site allows — 8, 10, 12, 20, or more. When a site has a maximum, use it. Longer is always better within whatever ceiling you're given.

Character set control. Toggle uppercase, lowercase, numbers, and symbols on or off independently. When a site says no symbols, turn them off. When it says alphanumeric only, you're covered. You get the strongest password possible within whatever rules the site imposes.

Multiple results at once. Generate a handful and pick the one that feels least unpleasant to type if you ever need to enter it manually. They're all equally strong — it's just a usability preference.

A generated password is strong. It's also completely unmemorable — which is the point. You were never supposed to memorize it.

This means you need somewhere to put it. Writing it on a sticky note defeats the purpose. Saving it in a plain text file on your desktop isn't much better.

The right answer is a password manager — a tool that stores your passwords securely, fills them in automatically, and means you only ever have to remember one thing. That's the next step, and it's worth doing before you generate passwords for anything important.

For now, use the generator for one account you've been meaning to secure. See how it works. The habit builds from there.
