Generate cryptographically secure random passwords of any length. Choose character types, exclude ambiguous characters, and generate up to 8 passwords at once. All generation happens in your browser — no passwords are ever sent to a server.
Strong passwords are your first line of defence against account breaches. Use a unique, random password for every account, and store them in a password manager.

How to Create a Strong Password
A strong password has four qualities: it is long (at least 12 characters, ideally 16+), it uses a mix of character types (upper, lower, numbers, symbols), it is random (not based on words or personal information), and it is unique (not reused across accounts).
8 characters: acceptable for low-risk accounts only. 12 characters: good for most accounts. 16 characters: strong, recommended for email and banking. 20+ characters: very strong, ideal for password manager master password.
Is this generator secure?
Yes. This generator uses the browser's crypto.getRandomValues() API, which provides cryptographically secure randomness — the same standard used by security software. Passwords are generated locally in your browser and are never sent to any server.
What to do with your passwords
Use a password manager (Bitwarden, 1Password, or your browser's built-in manager) to store and autofill passwords. Enable two-factor authentication (2FA) wherever possible. Never reuse passwords across sites — a breach at one service should not compromise others.
Frequently Asked Questions
Is this password generator safe to use?
Yes. All passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues). No password data is sent to any server, logged, or stored anywhere. The generation is cryptographically secure.
How long should my password be?
For most accounts: 16 characters minimum. For high-value accounts (email, banking, password manager): 20+ characters. Length is the single most important factor in password strength — a 20-character random password is exponentially harder to crack than a 10-character one.
Should I use a password manager?
Yes, absolutely. A password manager lets you use a unique, strong, random password for every single account without having to remember any of them. Bitwarden (free, open source), 1Password, and Dashlane are popular options. Your browser also has a built-in password manager.
What are ambiguous characters and why exclude them?
Ambiguous characters look similar in certain fonts: 0 (zero) vs O (uppercase O), 1 (one) vs l (lowercase L) vs I (uppercase i). Excluding them prevents confusion when you need to read or type the password manually, though for passwords stored in a password manager it does not matter.
Can I generate multiple passwords at once?
