How to Generate a Strong Password (and Why It Matters)

Weak, reused passwords are the most common cause of account breaches. A strong, unique password per site is the single biggest security upgrade you can make.

What makes a password strong?

• Length first. 16+ characters beats clever short ones. Length matters more than symbols.
• Randomness. Avoid names, dates, and dictionary words.
• Uniqueness. Never reuse a password across sites.
• A mix helps. Upper- and lower-case, numbers, and symbols widen the space.

Generate one safely

Use the free Password Generator:

1. Set the length (16+ recommended).
2. Choose character types; optionally exclude look-alike characters (0/O, 1/l).
3. Click generate and copy.

It uses your browser's secure random generator and never stores or transmits the password.

Manage them

You cannot remember dozens of strong passwords — use a password manager. For multi-factor setups, the Hash Generator and UUID Generator are handy developer companions.

Frequently asked questions

Are generated passwords stored? No. They are created locally and never saved or sent anywhere.

How long should a password be? Aim for at least 16 characters where the site allows it.

Random string vs. passphrase: how they compare

A random 16-character mix and a four-or-five-word passphrase (think correct-horse-battery-staple) can reach similar strength, but they trade off differently. Random strings pack the most entropy per character, so they're shorter — ideal when you let a password manager fill them and never type them by hand. Passphrases are far easier to type and recall, which makes them the better pick for the few secrets you actually memorize (your device login, your password-manager master password). The catch: a passphrase only stays strong if the words are randomly chosen, not a quote or a phrase you made up. When in doubt, generate a random string with the Password Generator for stored logins and reserve memorized passphrases for the handful you can't store. And if you run a service and need to define password rules for your users, a dedicated password policy generator helps you write sane requirements.
