Sign Documents With Your Face in Under 10 Seconds

Most people still think signing a document electronically means scribbling with a mouse or hunting for a saved image file. That's not signing — that's friction. GoodSign changed this with WebAuthn-based passkey signatures: a genuine industry-first that lets you sign documents with Face ID, Touch ID, or any biometric your device supports, instantly, every time.

No drawing. No typing your name. No uploading a signature image. Just your face or fingerprint, and it's done.

What Passkey Signing Actually Means

WebAuthn is the same open standard powering passwordless logins across Apple, Google, and Microsoft. GoodSign applies it to document signing — which means your signature is cryptographically tied to your device's biometric authentication, not a stored image anyone could copy.

The first time you sign, you draw or type your signature once and save it to your passkey. That's the only time you'll ever do it. Every document after that? One biometric scan and you're finished.

This isn't a gimmick. It's a fundamentally different model — one where your identity and your signature are verified together, at the hardware level, every single time.

Setting Up Your Signature Once

The setup takes about 60 seconds. When you open a signing request for the first time, GoodSign prompts you to create a saved signature using WebAuthn. You draw or type your signature, confirm it, and your device locks it to your biometric — Face ID on iPhone, Touch ID on Mac, fingerprint on Android, Windows Hello on PC.

SMS verification happens at this stage. Before your signature is saved, GoodSign confirms your phone number via text. This ties your identity to your passkey with a second factor from the start, not as an afterthought.

Once saved, that's it. Your signature exists as a passkey credential on your device. Nobody else can use it, and you never have to set it up again — not for that sender, not for any other document that supports passkey signing.

The Signer Experience From Document Two Onward

This is where the experience becomes genuinely remarkable. Someone sends you a contract. You open it on your phone. You tap the signature field. Face ID activates. Document signed.

The entire process takes under ten seconds. For anyone signing documents regularly — freelancers reviewing project agreements, agency clients approving proposals, small business owners handling vendor contracts — the cumulative time saved is significant. But more than time, it removes the mental friction that causes signing delays in the first place.

That friction is a real business problem. When signing feels like a chore, people procrastinate. Deals slow down. GoodSign's own data shows 65.3% of documents are signed within 24 hours — and a frictionless signing experience is a direct contributor to that number.

Why This Is More Secure Than Traditional E-Signatures

Touch ID electronic signature authentication and Face ID document signing aren't just convenient — they're measurably more secure than typed or drawn signatures.

Here's what makes the difference:

• Private keys never leave your device. The cryptographic key used to authenticate your signature is stored in your device's secure enclave and never transmitted. GoodSign never sees it.
• Biometrics authenticate the person, not just the device. Even if someone has your phone, they can't sign as you without your face or fingerprint.
• SMS verification adds a second layer at enrollment, confirming that the person setting up the passkey controls the phone number on record.
• A complete audit trail captures every signing event — timestamp, IP address, device, and biometric verification status — creating a legally defensible record.

Compared to a typed name or a dragged signature image, passkey document signing is in a different security category entirely. The audit trail alone makes disputes significantly easier to resolve.

Who This Is Built For

Passkey signing solves a specific problem: repeat signers who need speed and don't want friction. That's most people in a business context.

Freelancers sending the same contract structure to multiple clients. Agencies getting approval on creative briefs. Small and medium businesses processing vendor agreements, NDAs, onboarding documents. If someone signs more than a handful of documents a year, the passkey setup pays for itself immediately.

GoodSign's pricing model reinforces this. At $1.50 per envelope with no subscription and no user limits, there's no pressure to batch documents or limit who gets access to the tool. Every team member, every client, every occasional signer gets the
