Password Generator - Create Strong Secure Passwords
Create one strong password with a strength check. Need several at once? Use the Random Password Generator.
What Is a Password Generator?
A password generator creates strong, random passwords that are difficult for attackers to guess or crack. It uses cryptographically secure random values to ensure the generated passwords are truly random.
How to Use the Password Generator
- Select password length — Choose between 4 and 30 characters.
- Choose character types — Check or uncheck Uppercase, Lowercase, Numbers, and Symbols. Optionally include look-alike characters.
- Click "Generate" — One password appears with a strength rating. Each selected type is included at least once when length allows.
- Click "Copy" — Copy the password to your clipboard.
Password Strength Tips
- Use at least 12 characters — Longer passwords are exponentially harder to crack
- Include all character types — Mix uppercase, lowercase, numbers, and symbols
- Never reuse passwords — Use unique passwords for each account
- Use a password manager — Store your generated passwords securely
- Enable two-factor authentication — Add an extra layer of security
Why Password Strength Matters
Weak passwords can be cracked in seconds using automated tools. A strong password with 12+ characters including uppercase, lowercase, numbers, and symbols can take billions of years to crack using current technology.
