Human OTP: Verify Real People

Voices and faces can be faked — a shared secret can't. Confirm you're talking to the real person, and also keep all your 2FA codes in one private, offline place.

Prove it's really you — even on a call or over text.

Voices can be faked and messages can be spoofed, but a shared secret can't. Human OTP lets two people confirm they're really talking to each other, and keeps your website and app two-factor codes in the same private place. No account, no cloud, no tracking — everything lives on your phone.

Pair once, in person, by scanning each other's QR code. From then on, both phones show the same six-digit code that rolls over every 30 seconds. On a call or a text, read your code aloud — if it matches theirs, you know you're talking to the real them, not an impersonator or an AI voice.

Human OTP is also a full, standards-based authenticator for the accounts you already protect with two-factor authentication. Scan a site's setup QR or type its key, and your rotating codes live right beside your people.

What you can do

• Pair in person — scan a QR code once to share a secret key. No servers, no sign-up. • Match codes live — both phones show the same rotating six-digit code, in sync. • Confirm you're both real — read your code aloud to defeat impostors and deepfakes. • Discreet duress code — press and hold your own code to reveal an alternate that quietly signals you may be under pressure. No alarm, nothing a watcher can see. • Standard 2FA vault — add any website or app's two-factor account by QR or setup key (SHA1/256/512, 6–8 digits). • Home & Lock Screen widgets — glance at a contact's or account's current code without opening the app. • Lock it down — protect the app with a passcode and Face ID or Touch ID.

Private by design

Your contacts and secret keys never leave your phone. Keys are stored in the device Keychain, there's no account to create, and nothing is sent to a server or tracked. Pairing can work completely offline.

Meet once. Verify forever. Know you're talking to a real person — with Human OTP.
