Private signing links
Each recipient gets their own signing link. They can follow it to review and sign without creating a Linequill account.

Your documents.
Handled with care.
Clear controls for access, a deliberate signing process, and a record you can keep. Here’s how Linequill supports each part.
01 / DOCUMENT ACCESS
Shared with the right people.
Document access follows your workspace permissions and the private invitations you send.
Workspace permissions
Roles control who can view requests, prepare documents, or manage the workspace. Document files are served through access-controlled routes, not a public uploads folder.
Uploads are screened
Uploaded files go through malware screening before processing. If that screening is unavailable, the upload is blocked rather than accepted unchecked.
Encrypted connections
HTTPS protects the connection between your browser and Linequill. Stored document files use AES-256-GCM encryption, and server backups are encrypted separately.
02 / SIGNING SECURITY OPTIONS
Three levels. You choose the extra checks.
Start with a private signing link, then add phone verification or an ID barcode check. Your workspace policy sets the available choices and minimum requirements.
Standard
The signer opens their private invitation, agrees to the electronic signing statements, reviews the document, and signs. There is no separate email or SMS code, keeping the process simple for routine requests.
SMS verification
Adds a one-time code sent to the mobile number you provide for the signer. They enter that code before proceeding. This confirms access to that phone number, with short-lived codes and limits on retries.
Enhanced identity
Adds an ID barcode check after SMS verification. The signer uses their camera or selects a photo of a supported US or Canadian driver’s license barcode. The check compares the first and last name with the invitation and checks the expiry date.
03 / ACCOUNT PROTECTIONA little more protection.
A little more protection.
On your terms.
Use an authenticator app to add a second step to your account login. System administrator accounts require two-factor authentication.
Remember a browser you trust
After verifying a code, you can remember that browser for 30 days. You still need your password. New browsers ask for a code.
Stay in control of that choice
You can forget remembered browsers from your two-factor settings. Password or authenticator changes invalidate saved browser trust.
Support access has boundaries
A workspace owner must approve in-app support access. Approved sessions last 30 minutes, begin read-only, and are logged. Owners can revoke access and must separately allow draft or template edits.
04 / A RECORD OF THE PROCESS
More context around the signature.
Preparing, reviewing, and completing a request each contribute to its signing record.
Review and consent
The signing process asks recipients to review the document and confirm their agreement to the signing statements. Additional verification depends on the request’s settings.
Activity and completion details
The completion record includes recipient details, signing times, consent information, and recorded activity. These details provide context alongside the completed document.
A seal on the completed PDF
Linequill applies a cryptographic document seal to completed PDFs to help detect later changes. The document seal and the recipient’s signing information are separate parts of the record.
A FEW DETAILS, EXPLAINED
Good questions to ask.
Does a private signing link verify someone’s identity?
A private link provides access to the recipient’s signing request. Possession of a link alone does not independently verify a person’s identity. Additional verification depends on the controls required for that request.
Who can access stored documents?
Workspace permissions and private invitations govern document access. In-app support requires owner approval. Infrastructure administrators can technically access documents and server-managed encryption keys; this is not end-to-end encryption or a customer-managed key service.
How long are documents kept?
Documents are retained until a deletion request is reviewed. Signing-link expiry does not delete documents. Contact support about deletion or account closure, and download your records first.
Do all requests have the same verification steps?
No. Requests can use Standard, SMS verification, or Enhanced identity, depending on workspace policy. Compare the three signing security options and let recipients know what to expect before sending.
Can I keep a copy after signing is complete?
Yes. Completed documents can be downloaded and kept with your own records. Workspace owners and administrators can also download a ZIP of documents, activity records, and checksums from Settings > Data & access, or export an individual request. Download and check your records before requesting account closure. Our PDF signing guide walks through preparing, sending, and following a request through completion.
Where do I manage my account’s two-factor settings?
Open Account settings, then Two-factor authentication. You can connect an authenticator, replace recovery codes, and forget remembered browsers there. On shared devices, leave the remember-browser option unchecked.
