Are generated passwords stored anywhere?

No. Passwords are generated entirely in your browser using JavaScript — nothing is sent to a server, stored in a database, or logged anywhere. Close the tab and the password is gone permanently. You can verify this by running the tool in airplane mode: it works without any network connection.

What makes a password strong?

Length is the single most important factor. A 16-character password mixing uppercase, lowercase, numbers, and symbols has over 85 billion trillion (10²⁶) possible combinations. Character set diversity multiplies the search space: adding symbols to a numeric-only password increases it by orders of magnitude. Use a password manager so you only need to memorize one strong master password.

How long should my password be?

NIST Special Publication 800-63B recommends at least 12 characters for standard accounts and 16+ for sensitive accounts like email and financial services. For password manager master passwords, use 20+ characters since you only need to memorize one. The tool supports up to 128 characters — maximum entropy for high-value accounts.

Can I generate multiple passwords at once?

The tool generates one password per click, each cryptographically independent from the last. Click Generate repeatedly to produce multiple fresh passwords — there is no limit on how many you can generate in a session. Copy each password immediately since the display is overwritten on the next generation.

Free Strong Password Generator — Cryptographically Secure

A strong password generator creates random, unpredictable passwords using cryptographically secure randomness (the Web Crypto API). Unlike weak generators, this tool uses `crypto.getRandomValues()` so passwords cannot be predicted or reversed — no server, no tracking, nothing logged.

FAQ

Frequently asked questions

Yes. It uses the Web Crypto API (`crypto.getRandomValues()`), which is cryptographically secure and approved for security-critical applications. This is the same source of randomness used in TLS key generation and password manager libraries — not JavaScript's `Math.random()`, which is a pseudorandom number generator and entirely predictable by an attacker.
