Sign Once With Your Face. Never Draw a Signature Again.

Most people still think signing a document digitally means scribbling with a mouse or typing their name in a cursive font and hoping it counts. That friction costs real time — and for businesses sending dozens of contracts a month, it compounds fast. GoodSign just changed the equation entirely with passkey signing powered by WebAuthn, letting signers authenticate once via biometrics and apply their saved signature to any future document in seconds.

No drawing. No typing. Just Face ID or Touch ID, and it's done.

What Passkey Signing Actually Means

WebAuthn is the open standard that powers passkeys — the same technology behind passwordless logins on major platforms. GoodSign uses it to create a direct link between a signer's verified biometric data and their signature.

Here's how it works in practice: a signer receives a document, completes their signature the first time by verifying with Face ID or Touch ID, and that signature gets saved to their passkey profile. Every subsequent document they receive? One biometric prompt, and the signature is applied instantly. No setup screens. No typing. No hunting for a stylus.

This is what Touch ID document signing and sign documents with Face ID look like when they're built properly — not bolted on as an afterthought.

Why This Is an Industry-First Feature

Traditional eSignature platforms treat every signing event as a fresh experience. You open the document, find the signature field, draw something illegible with your trackpad, and wonder if it'll hold up legally. Some platforms added biometric authentication to their apps, but that just unlocks the app — it doesn't connect your identity to your actual signature.

GoodSign's biometric eSignature implementation goes further. The WebAuthn passkey binds the signer's verified identity — confirmed by the device's biometric hardware — directly to the signature record. This happens at the cryptographic level, not just the UI level. No other mainstream eSignature provider currently offers this as a standard, out-of-the-box feature for all senders and signers.

For freelancers, agencies, and small businesses sending contracts regularly, this changes the entire rhythm of getting work signed.

The Security Case for Biometric Signer Verification

Skeptics sometimes assume convenience means compromise. With passkey signing, the opposite is true.

When a signer verifies with Face ID or Touch ID, the device's secure hardware generates a cryptographic key pair. The private key never leaves the device. What gets recorded is proof that a specific, verified person authenticated the signing event — not just that someone clicked a button on a particular email link.

This matters for a few reasons:

• Signer identity is hardware-bound. Stolen credentials can't be used to impersonate a signer, because the biometric check happens on the signer's own device.
• Each signature event is cryptographically unique. There's a verifiable audit trail that links the document, the timestamp, and the biometric authentication event together.
• No stored passwords or PINs to breach. The passkey approach eliminates the most common vector for identity fraud in document signing.

For businesses in industries where signer verification matters — real estate, legal, finance, healthcare — this level of assurance has historically required expensive enterprise tiers or dedicated identity verification add-ons. Here, it's built in.

What This Means for Signing Speed

Speed and security usually trade off against each other. Passkey signing is one of the rare cases where improving one genuinely improves both.

65.3% of documents sent through GoodSign are signed within 24 hours. Reducing the friction of the signing experience is a direct driver of that number. When a returning signer doesn't have to fumble through a drawing interface or re-type their name, they're far more likely to sign immediately — on their phone, in between meetings, without needing a desktop.

For a freelancer waiting on a signed contract before starting work, or an agency trying to close a client before month-end, that speed difference is the difference between a deal done and a deal delayed.

No Subscription Required to Access This

It's worth being direct about something: features like biometric signer verification are typically locked behind enterprise plans at the major eSignature platforms. The pricing logic is that power features justify premium tiers.

GoodSign doesn't operate that way. At $1.50 per envelope with no subscription and no user limits, every feature — including WebAuthn passkey signing — is available on every send. A five-person agency
