The password is the only wall between hacker and your data. Rules: length beats complexity (16 chars beat "P@ssw0rd"), unique per site (a password manager saves you — Bitwarden, 1Password), change on leaks. 2FA is the second check: app code not SMS (SIM gets cloned). Phishing is "your account is blocked" mails with fake links.
- ●A password manager makes 20-char monsters and remembers them
- ●Check the domain: paypa1.com ≠ paypal.com — one letter steals the account
- ●Nobody asks for your password on the phone — not even "bank" or "police"
🔐 haveibeenpwned.com shows if your passwords leaked. 80% of people have at least one compromised. Check and change.
