Free Online Strong Password Generator
Create secure, random passwords that are virtually impossible to crack. This generator uses your browser's cryptographically secure random number generator (crypto.getRandomValues) to produce truly random passwords — no patterns, no predictability. Your passwords are never stored, transmitted, or logged anywhere.
What Makes a Strong Password?
A strong password is at least 12 characters long (16+ recommended), uses a mix of uppercase and lowercase letters, numbers, and symbols, doesn't contain dictionary words or personal information, and is unique for every account. This generator handles all of these requirements automatically.
How Secure Are These Passwords?
A 20-character password using all character types has approximately 130 bits of entropy. At current computing speeds, it would take billions of years to brute-force crack such a password. Even with quantum computing advances, passwords of 16+ characters with mixed character types remain secure for the foreseeable future.
Frequently Asked Questions
Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same randomness source used by password managers and encryption software.
No. All password generation happens entirely in your browser. Nothing is sent to any server, saved in any database, or logged in any way. When you close this page, the passwords are gone.
For most accounts, 16 characters is excellent. For high-security accounts (banking, email, password manager master password), use 20+ characters. The minimum acceptable length for any online account is 12 characters.
Characters like 0/O, 1/l/I, and backtick/quote can be hard to distinguish in certain fonts. Excluding them is useful when you need to manually type or read a password aloud, such as sharing a WiFi password.
