🎓 Password Security Best Practices

What Makes a Strong Password?

  • Length: At least 12 characters (16+ is better)
  • Uppercase Letters: Include A-Z
  • Lowercase Letters: Include a-z
  • Numbers: Include 0-9
  • Symbols: Include !@#$%^&*()_+-=[]{}|;:,.<>?
  • Unpredictability: Avoid patterns and common words

What to Avoid

Common Words: "password", "admin", "welcome". Personal Info: Names, birthdays, addresses. Patterns: "123456", "qwerty", "abc123". Substitutions: "P@ssw0rd" is still weak. Short Passwords: Under 8 characters are easily cracked.

Password Creation Methods

Random Generation: Use password managers to create truly random passwords. Passphrases: Combine 4-5 random words: "correct-horse-battery-staple". Sentence Method: Take first letters: "I love to eat pizza on Fridays!" = "Ilt2ep0F!"

🛡️ Real-World: Account Security

Scenario: Creating password for banking app

Weak Attempt: "mybank2024" - Score: 30/100

Strong Password: "B@nk!ng$3cur3#2024" - Score: 95/100

Result: Account protected from common attacks!

❓ Frequently Asked Questions (FAQ)

How does the password strength checker work?
The checker analyzes your password for length, character variety, common patterns, and dictionary words. It calculates a strength score based on these factors.
Is it safe to enter my password?
Yes! All checking happens in your browser. We don't store, save, or transmit your password anywhere. Your password is completely private.
What makes a password strong?
Strong passwords are long (12+ characters), use mixed character types (uppercase, lowercase, numbers, symbols), avoid common words, and are unpredictable.
How long should my password be?
Minimum 12 characters, but 16+ is recommended for important accounts. Longer passwords are exponentially harder to crack.
Should I use the same password everywhere?
No! Always use unique passwords for different accounts. If one is compromised, others remain safe. Use a password manager to track them.
Are password managers safe?
Yes! Reputable password managers use strong encryption and are much safer than reusing weak passwords or writing them down.
What about two-factor authentication?
Two-factor authentication (2FA) adds extra security beyond passwords. Always enable it when available for important accounts.
How often should I change passwords?
Change passwords if you suspect compromise or after a data breach. Otherwise, strong unique passwords don't need regular changes.
Can I use passphrases instead?
Yes! Passphrases like "correct-horse-battery-staple" can be both secure and memorable if they're long and random enough.
Will this work on my phone?
Yes! The password strength checker works perfectly on smartphones and tablets. Check password security anywhere.
