How Strong Is Your Password? A Practical Guide to Staying Secure Online

Passwords are still the first — and often the only — line of defence between your personal data and anyone who wants to get at it. Yet most people still rely on weak, easy-to-guess passwords, or reuse the same one across dozens of accounts. It only takes a single breach for all of them to be exposed.

The good news is that creating a genuinely strong password doesn’t have to be hard. In this guide we’ll look at what makes a password secure, the difference between passwords and passphrases, and how you can generate a strong one for free in seconds.

What makes a password strong

Three things matter most:

Length. The longer a password is, the harder it is to crack. A modern computer can try billions of combinations per second, so every extra character increases the time required exponentially. Aim for at least 16 characters.

Randomness. A password based on words, names, birthdays, or predictable patterns (like “123456” or “password”) is easy prey. A genuinely secure password is random.

Uniqueness. Never reuse the same password across accounts. If one leaks, you don’t want it taking all your other accounts down with it.

Passwords vs. passphrases

There are two good approaches, depending on how you’ll use them:

A random password (for example k7$Rm2!pX9qWn4z) is the strongest option for accounts you let a password manager remember for you.

A passphrase — several random words joined together, like Tiger-Maple-River-Cloud-42 — is easier to type or memorise while remaining extremely hard to crack. It’s an excellent choice for the master password of your password manager, or for your device login.

Generate a strong password for free

Rather than trying to think of something random yourself — which, ironically, humans are very bad at — you can use a tool that does it properly. This Free Password Generator creates strong, random passwords and passphrases in seconds, with controls for length, symbols, numbers, and more.

Crucially, all of the generation happens locally in your browser. The password is never sent, stored, or logged anywhere — something you can verify for yourself, since the tool uses your browser’s cryptographically secure random number generator rather than any server.

How to use it properly

1. Open the Online Free Password Generator.
2. Choose whether you want a random password or a passphrase.
3. Set the length and which character types to include.
4. Click generate and copy the result.
5. Store it in a reputable password manager — not in a notes app, an email, or on a sticky note.

A note on building tools like this

As a web developer, I built this tool partly to be genuinely useful and partly to demonstrate something I care about: that even a small utility should be built correctly. It runs entirely client-side, uses a cryptographically secure random source, and collects nothing — because a security tool that quietly transmits your passwords would defeat its own purpose. Good engineering is in the details, and a password generator is a small but honest example of that.

Conclusion

Online security starts with the basics, and a strong, unique password for every account is one of the most effective steps you can take. With a good tool, there’s no longer any excuse for weak passwords.
