✨ Password Security Tips
Use a Long Password (12+ characters)
Longer passwords are exponentially harder to crack. Aim for at least 12-16 characters.
Mix Character Types
Combine uppercase, lowercase, numbers, and special characters (!@#$%^&*).
Avoid Common Patterns
Don't use sequences (abc, 123), repeated characters (aaa), or keyboard patterns (qwerty).
Don't Use Personal Information
Avoid names, birthdays, addresses, or anything that can be found on social media.
Use a Password Manager
Let a password manager generate and store unique, strong passwords for each account.
Use Passphrases
Create memorable passwords using random words: "correct-horse-battery-staple"
📋 How to Use the Password Strength Checker
- Type a password into the box. The eye icon shows or hides it.
- Watch the strength meter and the feedback update as you type.
- Follow the suggestions to make it stronger.
🎯 When to Use It
- Checking whether an idea for a password is long and varied enough.
- Learning what makes a password weak, such as short length, common words or predictable patterns.
- Showing others why a short password is risky.
💡 Tips & Common Pitfalls
- Length matters most. A long passphrase beats a short password with symbols.
- Don't test a password you currently use for a real account. Test a similar one instead.
- Avoid names, birthdays, keyboard runs and common words, even with the usual number swaps.
- Use a password manager so every account has a different password.
❓ Frequently Asked Questions
Is this tool safe to use?
Yes! Your password is analyzed entirely in your browser using JavaScript. It is never sent to any server or stored anywhere.
What makes a strong password?
A strong password is long (12+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, and doesn't contain predictable patterns or dictionary words.
How is crack time calculated?
Based on password length, character variety, and common attack methods. Actual crack time varies based on attacker resources and methods used.
Should I use the same password everywhere?
Never! Use unique passwords for each account. If one is compromised, others remain safe. Use a password manager to track them.
