Why Password Strength Matters
Brute-force attacks use automated scripts to try millions of character combinations per second. Short or predictable passwords (like "password123") can be cracked in milliseconds. A truly strong password should be a random-looking collection of characters that is difficult for both humans and machines to guess.
🔒
Unique
Never reuse passwords across different accounts.
📜
Length
Complexity is good, but length is even better. Aim for 12+.
🔑
Manager
Use a password manager to store high-entropy secrets safely.
