Family code words: what they are and how to use one

Updated October 16, 2026 · 5 min read

A family code word is a secret word or short phrase that only your family knows, used to prove that someone on the phone is really who they say they are. It’s the same idea as a family safe word, and it matters more now that voices can be copied. Here is how to choose one and, more importantly, how to use it.

What a family code word does

When a call asks for money or secrecy, you ask for the code word. A real family member knows it. A scammer, even with a copied voice and your family’s names, has no way to guess it. That single question is the difference between a call you question and a call you act on.

How to choose one

  • Use two or more unrelated words, like “copper lighthouse”.
  • Choose something no one could find online: no pets, birthdays, addresses or school names.
  • Pick something easy to say aloud even when you’re upset.
  • Don’t reuse a password, PIN or security answer.

How to share it safely

Say it aloud, in person or on a call. Avoid sending it in a text or group chat, where it can be seen by anyone with the phone. If you must write it, keep it on paper in a private place, not on the fridge. Our guide to safe words covers more ways to share it.

Make it a habit

  1. Everyone says it aloud once.
  2. Agree when to ask for it: whenever money, secrecy or urgency is involved.
  3. Practise a pretend call so asking feels normal.
  4. Agree what to do if someone can’t say it: hang up and call back on a saved number.

Code word, safe word, password: are they the same?

Mostly. “Code word” and “safe word” are used interchangeably for this purpose. We explain the small differences in safe word vs code word.
