Password Generator
Generate strong, random passwords with your choice of character types and length, using a cryptographically secure random source — instantly, in your browser.
A strong password generator creates random passwords you can’t easily reproduce or guess, using a cryptographically secure random source rather than a predictable pattern. Choose your length and character types below — a password generates automatically, entirely in your browser.
How it works
Every character is chosen using crypto.getRandomValues(), the Web Crypto API’s cryptographically secure random number source — not Math.random(), which is fast but not designed to be unpredictable. No character types are excluded for “readability” — every class you enable (uppercase, lowercase, numbers, symbols) contributes its full range to the password.
FAQs
Is my generated password sent anywhere?
No. Passwords are generated entirely in your browser using your device’s secure random number generator — nothing is transmitted to or stored on our servers.
How long should my password be?
Longer is generally stronger. 16 characters with all four character types is a reasonable default for most accounts; use the maximum length a site allows for your most sensitive accounts.
Should I reuse a generated password across sites?
No — use a unique password for every account, ideally stored in a password manager, so a breach at one site can’t compromise your other accounts.
