Generate cryptographically strong, random passwords instantly. Customise length, character types, and complexity. No data is stored or transmitted — everything runs in your browser.
Weak passwords are the number one cause of data breaches worldwide. A password like "123456" or "password" can be cracked in less than a second. A 16-character random password with mixed character types, on the other hand, would take billions of years to crack using current computing power.
Every online account you own — email, banking, social media, business tools — deserves a unique, randomly generated password. Our free password generator creates cryptographically random passwords using your browser's built-in crypto.getRandomValues() API, ensuring true randomness without relying on predictable algorithms.
Length matters most. Every additional character exponentially increases the number of possible combinations. A 12-character password has 4,738 times more combinations than an 8-character password using the same character set. We recommend a minimum of 14 characters for important accounts.
Character diversity matters. Using a mix of uppercase letters, lowercase letters, numbers, and symbols dramatically expands the character pool — from 26 options (lowercase only) to 94+ options (all types combined). This makes brute-force attacks practically infeasible.
Randomness matters. Human-chosen passwords follow predictable patterns — capitalising the first letter, adding a number at the end, substituting "a" with "@". Attackers know these patterns. Machine-generated random passwords have no exploitable patterns.
Yes. This tool runs 100% in your browser. No passwords are transmitted to any server, stored in any database, or logged anywhere. The generation process uses the Web Crypto API, the same cryptographic engine used by banks and security software. You can verify this by disconnecting from the internet — the tool will continue to work perfectly.
