Secure Password Generator
Generate cryptographically secure passwords with entropy scoring. Custom length, charset & bulk generation.
Free Secure Password Generator — Random, Strong & Cryptographic
Toolify's Password Generator uses the browser's built-in `window.crypto.getRandomValues()` API — the same randomness source used by security professionals — to generate truly unpredictable passwords. Choose length (8–128 characters), character sets, and generate one or many passwords at once.
The entropy score shows how strong each password is in bits. Higher entropy means exponentially harder to crack. Aim for 100+ bits for sensitive accounts.
Frequently Asked Questions
What makes a password 'cryptographically secure'?
The tool uses the browser's `window.crypto.getRandomValues()` API, which generates random numbers from the operating system's entropy source (hardware random number generators). This is far more secure than Math.random(), which is predictable.
How long should my password be?
Security experts recommend at least 16 characters for most accounts, and 20+ for sensitive accounts like banking or email.
What is password entropy?
Entropy measures how unpredictable a password is, expressed in bits. Higher entropy means the password is harder to guess or brute-force.
Are the generated passwords stored anywhere?
No. Passwords are generated and displayed in your browser only and never saved or transmitted.
What is bulk password generation?
The bulk mode generates multiple unique passwords at once — useful for IT administrators setting up multiple accounts or testing systems.
