Signer identity
Who signed, shown by what the record keeps.
Attribution is the part of an e-signature most often thrown out in court, and it is several facts kept together, not one check. Here is what is recorded, and what is not.
What attributes a signature to a person
Weak evidence individually, considerably stronger together, and worthless if not captured at the moment. Every one of these is recorded on every signing.
A personal link
The signing link is minted for one named person and sent to their own phone number or email address. It is replaced rather than looked up, and nobody here can read it.
The typed name, checked
A signer types their full name, and it is checked against the name the link was sent to before the signature is accepted.
Address, browser and time
The network address, the browser and the moment of every event: sent, viewed, consented, signed. On the certificate, and never edited.
Consent, first
Agreeing to sign electronically is its own step with its own time, so the record can show it came before the signature rather than assert it.

One step stronger, when you choose it
A business that wants more than possession of the link can ask for it, per business, under Settings. The certificate then says so, in words that still do not say identity.
One-time passcodes
A six-digit code goes to the inbox or the phone the signing link went to, and must be typed before the person consents. It proves whoever is signing controls that inbox or phone at that moment, not only when the link arrived. Metered per code confirmed.
What the certificate says
Every signer's certificate carries an assurance level: reached by email, by text, in person, by a handed-over link, or one of the first two with a code confirmed. None of them is an identity check, and each says so.
ID Evidence
A photo of the signer's ID, and of themselves if they wish, taken after consent and before the signature. Kept encrypted for thirty days, seen only by your team, on the certificate by hash, and never checked against anything: evidence that somebody held that ID up when they signed, not a verification of who they are.

What is not offered yet
One stronger check is on the price list as not available yet, and it is listed here the same way. It is not behind an endpoint today, and this page will change the day it is.
ID document checks
A signer's government ID checked by a provider before they sign. Not available yet; ask if you need it, and we will say when.
Part of the record, not a badge on it
Attribution is one of five things, not a substitute for the other four. The document, the consent, the signature and the sealed record are what a certificate is made of.
On the certificate
Every signer, the method and value of their signature, and the address and browser at each step, frozen at issue and re-derived when checked.
Shown to the right people
The public check names the signers only to somebody who can show the document's fingerprint. Email addresses are never shown in public.
Kept to what is needed
Nothing is recorded that the record does not need. When a document is redacted, the addresses and browsers go with the text.
