💡 What makes a password strong?
✅Length matters most. Every extra character makes it exponentially harder to crack. Aim for at least 12, ideally 16 or more.
✅Mix it up. Combine uppercase and lowercase letters, numbers, and symbols like !, @, #, $, %.
✅Try a passphrase. Four random words joined together — like coffee-lamp-river-boat — are long, memorable, and very hard to crack.
❌Avoid personal info. Names, birthdays, pet names, and favourite teams are the first things attackers try.
❌Don't use common patterns. "Password1!", "Qwerty123", and "abc123" are on every attacker's list — no matter how "clever" they feel.
🔑Use your built-in password manager. On iPhone: Settings → Passwords. On Android: Settings → Google → Passwords. It generates and remembers strong passwords for you.
