Use strong passwords and add 2-factor authentication.
Add 2-factor authentication so that your email, social media and personal websites accounts don’t get held for ransom. Two-factor authentication is something you know (e.g., password, personal identification number (PIN)) plus something you have (e.g., smartcard, hardware token, USB drive with code).
Minimalize personal information on social media.
Be careful with what you post on social media; limit personal information that could be used against you. This could include personally identifying information (e.g., date of birth, home address), habit patterns (e.g., specific vacation dates that indicate when you will not be home), strong social and political opinions (e.g., ones that may attract undue attention), etc.
