Over 80% of hacking-related data breaches are caused by weak or reused passwords. A strong password is one of the simplest and most effective ways to protect your online accounts — email, banking, social media, and everything else.
Yes — completely. This tool uses your browser's built-in Web Crypto API to generate cryptographically secure random passwords. The passwords are created entirely on your device and are never transmitted to any server, never stored, and never logged. Only you see them.
Security experts recommend passwords of at least 12-16 characters. A 12-character random password with uppercase, lowercase, numbers and symbols has over 4 quadrillion possible combinations, making it extremely resistant to brute-force attacks.
A strong password is long (12+ characters), random, and uses a mix of uppercase letters, lowercase letters, numbers, and special symbols. It should not contain your name, birthday, or common words. A password generator ensures true randomness.
Never reuse passwords across different sites. If one site suffers a data breach, attackers use leaked passwords to try logging into other services. Use a unique password for every account, and a password manager to remember them all.
A passphrase is a sequence of random words, like 'purple-coffee-mountain-seven'. A 4-word passphrase can be easier to remember than a random character password while still being very secure. Aim for at least 4 random unrelated words totalling 20+ characters.
Yes. This password generator runs entirely in your browser using JavaScript's cryptographically secure random number generator (crypto.getRandomValues). No passwords are sent to any server or stored anywhere. Everything stays on your device.
The single most important factor in password strength is length, not complexity. A 20-character password made up of random lowercase letters is significantly harder to crack than an 8-character password with uppercase, numbers, and symbols. That said, combining length with character variety is the ideal approach. Security researchers have shown that passwords based on dictionary words, even with common substitutions like replacing "a" with "@" or "e" with "3", are vulnerable to modern cracking techniques that specifically test these patterns. A truly strong password is one generated randomly by a password generator, with no recognisable words, patterns, or personal information. Aim for at least 16 characters when possible, and always include a mix of character types for maximum entropy.
Modern security guidance has evolved well beyond simply choosing a strong password. The most important habit is to never reuse a password across multiple accounts. When a data breach exposes credentials from one service, attackers use automated tools to try those same credentials on thousands of other websites within minutes. A password manager such as Bitwarden, 1Password, or your browser's built-in manager lets you store a unique, randomly generated password for every account without having to memorise any of them. You only need to remember one strong master password. Beyond that, enable two-factor authentication on every account that supports it. Hardware security keys and authenticator apps provide far stronger protection than SMS-based codes. Finally, check your email address against breach databases periodically to find out if any of your accounts have been compromised, and change those passwords immediately using this password generator.
