Secure Password Generator
Generate strong, random passwords using cryptographically secure randomness. All generation happens in your browser—your passwords never leave your device.

Length Matters
Longer passwords are exponentially harder to crack. Aim for 16+ characters for important accounts.
Use a Password Manager
Don't try to remember complex passwords. Use a password manager to store them securely.
Unique Passwords
Never reuse passwords. If one account is compromised, others remain safe.
How to Generate Secure Passwords
- Set your desired password length (recommended: 16+ characters)
- Select character types to include (uppercase, lowercase, numbers, symbols)
- Optionally exclude similar characters (i, l, 1, L, o, 0, O) for clarity
- Click 'Generate' to create a cryptographically secure password
- Copy the password and store it securely in a password manager
Password Strength Examples
Strong Password (16 chars, all types)
Example: 'K#9mP@2vL$7xQ!w' - Very strong, estimated crack time: billions of years
Memorable Password
Example: 'Correct-Horse-Battery-Staple-42' - Easier to remember, still secure with word combinations
PIN Code
Example: '8472' - Numeric PIN for devices or quick access codes
Common Password Mistakes to Avoid
- Using short passwords (under 12 characters)
- Reusing passwords across multiple accounts
- Using personal information (names, birthdays, addresses)
- Using dictionary words without variation
- Not using a password manager to store complex passwords
Frequently Asked Questions
How secure are the generated passwords?
Passwords are generated using your browser's crypto.getRandomValues() API, which provides cryptographically secure randomness. This is the same method used by professional security tools.
Is my password data stored or sent anywhere?
No, all password generation happens in your browser. Nothing is stored or sent to any server. Your passwords never leave your device.
What makes a password strong?
A strong password is long (16+ characters), uses a mix of character types, and is unique. Entropy (randomness) is the key measure of password strength.
Should I use memorable passwords?
Memorable passwords using random words can be secure if they're long enough (4+ words) and include numbers or symbols. They're easier to remember but should still be stored in a password manager.
How often should I change my passwords?
Modern security best practice is to use unique, strong passwords and only change them if there's a security breach. Focus on using unique passwords for each account rather than frequent changes.
