🔐 Secure Password Generator

What makes a password secure?

A secure password is hard to guess for both humans and automated attacks (brute force, dictionary). Password security depends mainly on two factors:

• Length — Each extra character exponentially multiplies the time to crack it. Minimum 12, ideal 16+.
• Character variety — Combining upper, lower, numbers and symbols expands the attackable "alphabet".
• Randomness — Avoid patterns, common words, names or dates. Use cryptographic generators.
• Uniqueness — Never reuse the same password on multiple sites. If one leaks, all are lost.

Password security best practices

✅ What TO DO

• Use a password manager — Bitwarden, 1Password, KeePass are safe options.
• Enable 2-factor authentication (2FA) — Double security: password + temporary code.
• Unique password per site — Prevents domino effect if one leaks.
• Change passwords after breaches — Check haveibeenpwned.com if your email was compromised.
• Passphrases — Example: "Correct-Horse-Battery-Staple". Easy to remember, very secure.

❌ What NOT to do

• Use personal info — Name, birthday, pet, city are easy to find.
• Dictionary words — Dictionary attacks try millions per second.
• Obvious substitutions — Replacing "a" with "@" or "o" with "0" no longer fools attackers.
• Share passwords — Never by email, chat or SMS.
• Save in notes — Unencrypted text files are vulnerable.
