About Trust Onion

Our mission

Trust Onion helps families verify each other's identity. AI voice cloning and deepfake video have turned "is this really you?" into a question worth asking every time the phone rings. We build layered verification tools that let your family prove who they are, without giving up privacy or trusting a third party.

Why we built this

A phone call from "your grandchild" asking for bail money. A text from "your CEO" asking for gift cards. These scams used to require a con artist. Now they require three seconds of audio from a TikTok and a voice cloning app. The targets are the people least prepared to question a familiar voice: parents, grandparents, anyone who picks up the phone expecting good news.

We started Trust Onion because the tools that existed (password managers, security questions, callback lists) were built for identity theft, not for a panicked call at 11 PM. Families needed something that worked in seconds on any phone, with nothing to memorize or install ahead of time.

How it works

Trust Onion layers three lightweight verification tools on top of each other, like the layers of an onion:

• Codewords — time-based phrases generated locally on each family member's device. They rotate on a schedule and never leave the device.
• Proofies — biometric-verified selfies with the current codeword overlaid and cryptographically signed by the sender.
• Family groups — private circles where members exchange public keys to form a trust network only they control.

None of your codewords or selfies are stored on our servers. Your verification happens between you and the people you trust.

Who we are

Trust Onion is built by Alibi Ledger, LLC, a small team focused on practical defenses for everyday families. We are headquartered in Wyoming and work remotely across the United States.
