About the Password Generator

This password generator creates strong, random passwords to your chosen length and character mix, and rates their strength. Unique, high-entropy passwords are the single best defence against account compromise, and generating them removes the human tendency to pick guessable ones.

What makes a password strong

Strength comes from entropy — the number of possibilities an attacker must search. That grows with length and with the size of the character set (lowercase, uppercase, digits, symbols). A long password drawn randomly from a large set is exponentially harder to crack than a short one or a dictionary word with predictable substitutions. The generator lets you set the length and which character types to include, and estimates the resulting strength.

Crucially, generated passwords are random, so they avoid the patterns people fall into — names, dates, keyboard runs, and 'P@ssw0rd' tricks that attackers test first. Length usually buys more security than complexity, so a longer passphrase-length string is often the strongest practical choice.

Using them safely

A strong password only helps if it is unique to each account, so a breach of one site cannot unlock others. Because unique random strings are impossible to remember, store them in a reputable password manager, which also fills them in for you. Generate, save to the manager, and never reuse — that combination defeats the most common real-world attacks.

Worked example

Comparing the strength of two password choices.

A 6-character lowercase password has 26⁶ ≈ 300 million combinations — crackable fast.
A 16-character mix of cases, digits, and symbols has roughly 94¹⁶ combinations.
That is astronomically larger and infeasible to brute-force.

Length plus a full character set makes the 16-character password vastly stronger.

Frequently asked questions

What makes a password strong?

Length and randomness across a large character set. The more characters and the wider the mix of letters, digits, and symbols, the more combinations an attacker must try. Avoid words, names, and predictable patterns.

Is length or complexity more important?

Length generally wins. Adding characters increases the possibilities exponentially, so a long password — even of simpler characters — often beats a short, complex one. Best is long and varied.

How should I store generated passwords?

Use a reputable password manager so each account gets a unique, strong password you don't have to remember. Reusing passwords is the main reason one breach leads to others.
