Drag the length slider to choose how many characters you want — from 6 to 64. A length of 16 or more is recommended for strong security.
Tick the character sets you want to include — Uppercase (A–Z), Lowercase (a–z), Numbers (0–9), and Symbols (!@#$). Using all four produces the strongest passwords.
Enable No Ambiguous to remove look-alike characters (0, O, l, 1) for easier readability, or enable No Repeating Chars to ensure every character is unique.
Press the Generate button to instantly create a cryptographically secure password. The strength meter and entropy estimate update in real time.

Uses the browser's built-in crypto.getRandomValues() API — ensuring true randomness with no predictable patterns.
A live strength bar (Very Weak to Very Strong) and entropy estimate in bits update instantly as you change settings.
Mix and match uppercase, lowercase, numbers, and symbols. Toggle No Ambiguous or No Repeating Chars in one click.
Your five most recently generated passwords are displayed with individual copy buttons for quick retrieval.

Every password is generated entirely inside your browser. No data is ever sent to a server.
Passwords are generated using your browser's cryptographically strong crypto.getRandomValues() API, ensuring high randomness and security.
No, all passwords are generated locally inside your browser memory and are never sent to any server or saved externally.
A strong password is long (16+ characters) and combines uppercase letters, lowercase letters, numbers, and special symbols to maximize entropy.
A passphrase combines multiple random dictionary words, making it memorable for human users while maintaining extremely high entropy against automated guessing.
Security experts recommend a minimum length of 12 to 16 characters for general online accounts, and 20+ characters for critical master accounts.
