Certifyd CodeWords

When a request feels wrong,
check somewhere safer.

CodeWords gives you and the people you trust a separate way to check unusual calls, texts, emails, and video meetings before anyone sends money, shares access, or changes a plan.

CodeWords confirms an enrolled phone and a specific request. It does not prove a voice, email sender or legal identity.

How it works

Trust starts before the suspicious call.

Caller ID, a familiar voice and an email address can all be imitated. CodeWords creates a separate relationship between two enrolled phones first.

01

Connect while you are together

One phone shows changing signed QR frames. The other scans them and finds the matching nearby Bluetooth service.

02

Check both signals

The phones exchange a fresh signed Bluetooth challenge. Both people compare the same three words and six-digit number before accepting.

03

Challenge the exact request

Later, ask about the payment, password reset, file share or safety request itself. The other phone can confirm, deny or report pressure.

Two signals, one human check

A saved QR screenshot is not enough.

The beta scans three fresh, sequential QR frames, connects to the matching Bluetooth service, and verifies a fresh challenge signed by the presenting phone. Both people then compare the same short code before accepting.

Current beta limitation: the Bluetooth challenge is authenticated but not application-encrypted. It does not prove an exact distance, and a modified client or coordinated relay remains possible.

CodeWords for Personal Use

Give family and friends a safer way to check.

Connect with a parent, partner, adult child, relative, or close friend before an emergency. If a future request feels wrong, stop the conversation and check the exact action in CodeWords.

Are you asking me to buy gift cards during this call?
Are you safe and asking me to collect you?

CodeWords for Business

Make it normal to challenge unusual instructions.

Build trusted links between colleagues first, then extend them to named suppliers and clients. CodeWords gives each relationship a separate signed path for checking the exact request before anyone acts.

Are you asking me to change the supplier bank account?
Are you asking me to share the payroll file with this address?
Are you asking me to reset the administrator password?

CodeWords adds a layer of trust, but the team must use it. Make pausing and checking expected, even when an urgent request appears to come from a senior leader. Keep dual approval, independent call-backs, and account controls in place.

What a result means

Confirm the device and the request, not the caller’s identity.

A valid confirmation means

  • The previously enrolled phone responded.
  • The responder opened CodeWords and approved the displayed request.
  • The signed answer is fresh, time-limited and bound to those details.

It does not prove

  • That a voice, video image, email address or legal identity is genuine.
  • That the phone is not stolen and already unlocked.
  • That the person is free from coercion or that the requested action is safe.
