What is a Password Generator?
A password generator is a free online security tool that creates strong, random passwords based on your specified criteria. Instead of using weak, predictable passwords like "password123" or "qwerty," a password generator produces cryptographically random strings of characters that are virtually impossible to guess or crack.
Our advanced password generator gives you full control over password creation. You can adjust the length from 4 to 128 characters, choose which character types to include (uppercase, lowercase, numbers, symbols), exclude ambiguous or similar characters, prevent repeating or sequential characters, and even generate up to 50 passwords at once.
How to Generate a Strong Password
Creating a secure password with our free tool takes just a few seconds:
- Step 1 — Set Password Length: Use the slider or type a number to set the desired length. We recommend 16+ characters for maximum security.
- Step 2 — Choose Character Types: Toggle uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols (!@#$%) on or off based on your needs.
- Step 3 — Apply Extra Options: Enable options like excluding ambiguous characters, preventing repeats, or blocking sequential characters.
- Step 4 — Set Quantity: Choose how many passwords to generate (1 to 50 at once).
- Step 5 — Generate & Copy: Click "Generate Passwords" and use the copy button next to each password to paste it where needed.
Password Security Best Practices
Follow these guidelines to keep your accounts secure:
- Use at least 16 characters: Longer passwords are exponentially harder to crack. A 16-character password with mixed characters is practically unbreakable.
- Mix character types: Combine uppercase, lowercase, numbers, and symbols for maximum entropy.
- Never reuse passwords: Use a unique password for every account. If one account is compromised, the others remain safe.
- Avoid personal information: Don't use birthdays, names, addresses, or any information someone could guess about you.
- Use a password manager: Store your generated passwords in a reputable password manager like Bitwarden, 1Password, or KeePass.
- Enable two-factor authentication: Add an extra layer of security beyond your password wherever possible.
- Change passwords regularly: Update passwords for critical accounts every 3-6 months.
Understanding Password Strength
Password strength is measured by how resistant a password is to brute-force and dictionary attacks. Our tool displays a real-time strength meter based on these factors:
- Length: Each additional character exponentially increases the number of possible combinations.
- Character pool size: More character types mean more possibilities per position.
- Unpredictability: Randomly generated passwords are stronger than human-chosen ones because humans tend to use predictable patterns.
- Entropy: Measured in bits, entropy quantifies the unpredictability. A 16-character password with all character types has approximately 105 bits of entropy.

Frequently Asked Questions
What is a password generator?
A password generator is a free online tool that creates strong, random passwords based on your specified criteria such as length, character types (uppercase, lowercase, numbers, symbols), and exclusion rules. It uses cryptographic randomness to ensure maximum security.
How long should a strong password be?
For maximum security, passwords should be at least 16 characters long. For general use, 12-16 characters is recommended. Our password generator lets you create passwords from 4 to 128 characters to match any requirement.
What makes a password strong?
A strong password combines uppercase letters, lowercase letters, numbers, and special symbols. It should be at least 12 characters long, avoid dictionary words, and not use predictable patterns like birthdays or names.
Is this password generator secure?
Yes. Our password generator uses the browser's cryptographic random number generator (crypto.getRandomValues) for true randomness. All passwords are generated locally in your browser — none are transmitted to or stored on any server.
Should I use the same password for multiple accounts?
No. You should use a unique password for every account. Reusing passwords means that if one account is compromised, all accounts with the same password are at risk. Use our generator to create a unique password for each site.
Can I exclude similar-looking characters?
Yes. Our password generator includes options to exclude ambiguous characters (like 0/O, 1/l/I) and similar characters. This is useful when creating passwords that need to be read aloud or typed manually.
How many passwords can I generate at once?
You can generate up to 50 passwords at once using our batch generation feature. This is useful when you need to create passwords for multiple accounts or users.
How do I copy a generated password?
Click the copy button next to any generated password, or click the "Copy All to Clipboard" button. The password will be copied to your clipboard and is ready to paste wherever you need it.
