📏
Length Wins
A 20-character password is exponentially harder to crack than a 10-character one. Aim for 16+ characters minimum.
🎲
Use a Passphrase
Random words strung together are both strong and easy to type. Example: apple-storm-velvet-zeal
🚫
Avoid Dictionary Words
Hackers use wordlists with millions of common passwords. Substituting a with @ or o with 0 is known and does not help much.
🔑
Unique Per Site
If one site leaks your password, attackers try it everywhere. Use a password manager to keep unique credentials for every account.
📱
Enable 2FA
Two-factor authentication adds a second layer even if your password is compromised. Use an authenticator app over SMS when possible.

Entropy Matters
Entropy measures randomness. 128 bits is considered quantum-safe. This tool shows your entropy so you know exactly how strong you are.
