🔐 Why Strong Passwords Matter
Weak passwords are one of the leading causes of hacked accounts. A strong password should be long, random, and unique for every account. Our Password Strength Checker helps you test passwords, estimate how long they would take to crack, and generate secure alternatives.
The tool also includes a password generator that creates random, high-entropy passwords up to 64 characters long. You can include uppercase letters, lowercase letters, numbers, and symbols. Every generated password is created locally in your browser and is never sent to any server.
🛡️ Password Security Tips
- Use at least 12-16 characters for important accounts.
- Avoid common words, birthdays, and sequential numbers like "123456".
- Use a different password for every account.
- Enable two-factor authentication whenever possible.
- Consider a reputable password manager to store complex passwords.
