EXAMPLE
EXAMPLE — Calculatore.net

❌ Using personal info: Birthdays, pet names, anniversaries — all easily found on social media

❌ Reusing passwords: A breach on one site compromises all your accounts

❌ Simple patterns: Password1!, Qwerty123!, Admin2026!

❌ Keyboard walks: qwerty, asdfgh, 1qaz2wsx

Best Practices for 2026

1. Use a password manager — Bitwarden, 1Password, or Apple Passwords

2. Enable 2FA everywhere — Two-factor authentication adds a second layer

3. Use passphrases — Combine 4+ random words: "Blue-Coffee-Rocket-Piano-72!"

4. Generate random passwords — Use our Password Generator

5. Change passwords after breaches — Check haveibeenpwned.com
