How it Works?

Securely send and e-sign documents on the go with OneSpan Sign’s mobile app

The OneSpan Sign electronic signature mobile app provides a convenient way to send and e-sign documents from your mobile device. Users that already have a OneSpan Sign account can access their account from the mobile app at no extra charge.

Easy to Use

Designed with the user experience of senders and signers in mind

Enables business users to quickly prepare documents and invite people to sign them using drag-and-drop features

upload a document

UPLOAD A DOCUMENT: Upload the document that needs to be signed from popular cloud storage services such as Box or Google Drive. Documents can also be uploaded from your device’s photo library.

add signers

ADD SIGNERS: Add signers to the transaction by entering their email address or directly import the signer info from your device’s contact list. What’s more, you can specify signing order and use authentication methods to validate your signers’ identity.

prepare and send documents

PREPARE & SEND DOCUMENTS: Drag and drop signature blocks and data capture fields into the document, then click “Send” to send signers an email notification inviting them to sign the document.

track status

TRACK STATUS: The sender can monitor the status of all documents to be signed via the application’s dashboard. The sender is also notified by email when each signer has signed the document.

Prompts people to sign and initial in all the right places, and prevents documents from being returned if missing


SIGNING INVITATION: The signer receives an email invitation with a link to access the document to sign. For added security, the signer may be asked to authenticate their identity before accessing the document if requested by the sender.

review and sign

REVIEW & SIGN: The signer is guided to sign, initial and enter additional signing information into the document. Once signed, the document is automatically routed back to the sender, or to the next person who must sign the document.

review and sign

REVIEW & SIGN: The signer is emailed a link to the completed document once every person has signed. The signer can then download the final e-signed documents.

The Beginner’s Guide to Electronic Signatures

This comprehensive, 31-page beginner’s guide to electronic signatures introduces important legal concepts and key considerations when creating digital business processes with e-signatures.

Security and Compliance

Prove your compliance and deflect legal disputes with our audit trail

audit trails

Captures identity verification, authentication, and e-signature events of the entire agreement process in a single, unified audit trail.  Our audit trail provides a more complete picture of the transaction with strong identity assurance to demonstrate compliance for remote processes.

Compare Static and Visual Audit Trails

Static Audit Trail

Captures what was signed

OneSpan Sign captures standard audit trail information, such as who signed, what document, when (time-stamp), where (IP address), in what order, and how. The static audit trail is embedded directly in the document, making it easier to verify and store e-signed documents as a single, portable file.

Visual Audit Trail

Captures all information presented to users during the web transaction

OneSpan Sign is the only solution to capture active visual audit trail of all information presented to users that helped build their understanding of what there were signing. This includes consenting to OneSpan Sign, all disclosures, and other web screens. This makes it faster, easier and less costly to prove your compliance and build your legal case.

Secure your documents and each person’s signature using military-grade, digital signature technology

OneSpan Sign guarantees document integrity by applying a digital signature and tamper seal after each person has signed, and then automatically detecting if a change is made in between signers. And unlike other providers, OneSpan Sign embeds the audit trail directly in the document, enabling you to instantly verify it with just one click.

Compare OneSpan Sign's Security with the Competition

Digital Signature for EACH & EVERY Signer

OneSpan Sign secures each person’s signature in the document using digital signature technology so that if a change is made in between signers, their signature is visibly invalidated. This deters fraud and provides a more reliable audit trail. The audit trail is directly embedded in the document, resulting in a single file that’s easier to verify and manage.


Digital Signature for ALL Signers

Some other e-signature solutions only apply a tamper seal wrapper at the end of the signing process, enabling the document’s content to be modified without detection in between signers. What’s more, their audit trail is only available as a separate file, forcing you to store two files and making it longer to verify.

Built on leading infrastructure services from Amazon, IBM and Microsoft to ensure high application security


Keep your company and customer data safe using Advanced Encryption Standard (AES) 256-bit encryption. OneSpan Sign complies with SOC 2 Type II, HIPAA, FedRAMP and other stringent industry security and privacy requirements. See the summary of the auditor’s report at the Trust Center.
