How to Use Password Generator
Configure Length
Use the slider to set your desired password length (8–64 characters). Longer passwords are more secure — we recommend at least 16 characters for important accounts.
Choose Character Sets
Select which character types to include: uppercase letters, lowercase letters, numbers, and symbols. Including all four types creates the strongest passwords.
Generate Password
Click "Generate" to create a cryptographically secure random password. Each generation uses the Web Crypto API for true randomness.
Copy and Use
Click "Copy" to copy the password to your clipboard. Use it immediately — we never store or transmit your password.
Example Password
xK9#mP2$vL7@nQ4*wR8 20 characters, all character types — ~95²⁰ possible combinations.
Frequently Asked Questions
How secure are the generated passwords?
Our passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same API used by password managers and security applications. The security depends on length and character set — a 16-character password with all character types has approximately 95¹⁶ possible combinations.
What makes a strong password?
A strong password should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid common words, personal information, and predictable patterns. The best passwords are randomly generated — human-created passwords tend to follow predictable patterns.
Is it safe to use an online password generator?
Yes, our tool is completely safe because all processing happens locally in your browser. Your password is never sent to any server, never stored, and never logged. You can verify this by disconnecting from the internet after loading the page — the generator will still work.
How long should my password be?
For most accounts, 12–16 characters is sufficient. For highly sensitive accounts (email, banking, password manager master password), use 20+ characters. Each additional character exponentially increases the time required to crack the password.
Password Security Best Practices
