Most identity fraud does not need hacking. It needs details: your full name, date of birth, address, mother's maiden name, school, pet, phone number. Many of those are sitting on social media, posted with the best intentions. A little restraint makes you a much harder target.

Privacy settings to check

  • Who can see your posts, friends list and photos.
  • Whether your phone number and email are visible.
  • Location tagging on photos.
  • Whether search engines can find your profile.

Before posting, ask: would I be comfortable if a stranger who wanted to impersonate me saw this?

Already posted something?

Delete or restrict it, change any security answers it revealed, and for exposed card or ID details, contact the issuer. See leaked ID numbers.

Frequently asked questions

Is it dangerous to post my birthday?

Your full date of birth is often used to verify identity. Showing the day but not the year, or keeping it private, reduces risk.

Why shouldn't I post my boarding pass?

The barcode and booking reference can reveal personal details and let someone access or change your booking.

Is posting holiday photos while away risky?

It can tell people your home is empty and helps scammers target family with 'emergency' stories. Consider posting after you return.
