Password Generator
Create strong, secure, random passwords instantly — 100% private
Generate a strong, random password in your browser: choose the length and whether to include uppercase letters, lowercase, numbers and symbols. Every password is created on your own device using its built-in cryptographic randomness and is never sent anywhere or saved, so the one you generate is seen only by you.

What actually makes a password strong
The two things that make a password hard to crack are its length and its unpredictability, and length matters more than most people realise. A short password bristling with symbols is weaker than a long one made of ordinary words, because every extra character multiplies the number of combinations an attacker has to try. A random string of sixteen characters, or a passphrase of four or five unrelated words, beats the old "P@ssw0rd!" pattern comfortably.
Just as important is never reusing a password across sites: when one service is breached — and breaches are constant — reused passwords let attackers walk straight into your other accounts. The realistic way to manage that is a password manager, which remembers a unique long password for every site. Because the generator here runs entirely on your device, you can create those passwords without any of them touching the internet.
❓ Frequently Asked Questions
Are these passwords safe to use? ▼
Yes. Passwords are generated entirely in your browser using crypto.getRandomValues() — your device's cryptographically secure random number generator. Nothing is ever sent to a server, logged, or stored. When you close the page, the password is gone unless you saved it.
How long should my password be? ▼
Use at least 16 characters for important accounts. Longer is always stronger — a 16-character password with mixed character types would take billions of years to crack by brute force. For maximum security on critical accounts, use 20+ characters.
What is a passphrase and is it more secure? ▼
A passphrase strings together random words (e.g. Tiger-Cloud-Maple-Frost42). They're far easier to remember than random strings while still being very strong thanks to their length. Switch to "Memorable passphrase" mode above to generate one.
Why exclude similar characters? ▼
Characters like l (lowercase L), 1 (one), I (capital i), 0 (zero) and O (capital o) look almost identical in many fonts. Excluding them makes a password easier to read and type by hand without losing meaningful security.
