## Description

Grandparent scams, fake bank agents, eerily real AI voices? ContactKey lets you confirm — in a call, chat or video — that the right person is really on the other end.

The digital safeword for family & friends.

Scammers impersonate family, your bank, your boss or the authorities – and with AI, faked voices now sound disturbingly real. ContactKey gives you a simple tool against it: a shared safeword.

How it works:
1. Set it up once, in person: you scan each other's QR code. It takes seconds.
2. From then on, ContactKey always shows you the same safeword, which changes regularly. Say it to each other on your next call or chat – if it matches on both phones, you recognize and identify each other.

No one else can know your safeword.

Privacy by design:
• Fully offline – no servers, no cloud, no telemetry
• No account, no phone number and no email required
• Your keys never leave your phone
• Source-available – the code is auditable

ContactKey helps against:
• Grandparent & emergency scam calls
• Fake bank and support agents
• CEO / fake-boss fraud
• Deepfake voices and videos
• Phishing and social engineering

Perfect for families, friends and teams who want to keep each other safe.

Personal · Simple · Offline

Important: a matching safeword confirms the connection you set up in person – it is not proof and does not replace caution. Whether you share sensitive information on that basis remains your own free decision.
