Generate strong, random, secure passwords with adjustable length and character sets. Cryptographically random and 100% client-side.
Last updated 23 June 2026 · Built and maintained by Mustafa Bilgic
This password generator builds strong, unpredictable passwords using your browser's cryptographically secure random number generator (the Web Crypto API). It never reuses patterns, never stores your passwords, and never sends them to a server. Choose your length and character sets, then click Generate.
| Length | Character Set | Strength |
|---|---|---|
| 8 | All types | Weak by modern standards |
| 12 | All types | Good for low-risk accounts |
| 16 | All types | Strong, recommended default |
| 20+ | All types | Excellent for sensitive accounts |
Yes. The generator uses crypto.getRandomValues from the Web Crypto API, which provides cryptographically secure random values rather than the predictable Math.random().
No. Generation happens entirely inside your browser. No password is transmitted, logged, or stored on any server, so it is safe to use for real accounts.
For important accounts, use at least 16 characters with mixed types. Longer is always stronger; 20 or more characters is excellent for email and banking.
It removes look-alike characters such as 0, O, 1, l, and I so the password is easier to read and type without errors, at a small cost to the character pool size.
Each extra character type multiplies the number of possible combinations, making brute-force attacks dramatically slower. Keeping all four types enabled gives the strongest result.
