A Digital Certificate in SignNow provides an added layer of security, authenticity, and compliance for your electronic signatures. It verifies the signer’s identity, prevents tampering, and guarantees that the document remains unchanged after signing. This makes it an essential feature for organizations that manage sensitive, high-value, or legally binding documents. With a digital certificate, each signed file includes verifiable proof of authenticity and integrity — strengthening trust, meeting regulatory requirements, and ensuring your eSignature workflows are both secure and compliant.
Using a digital certificate with SignNow enhances the security, authenticity, and legal validity of your eSignatures — especially in industries or use cases that demand high levels of trust and compliance. It provides non-repudiation, a complete audit trail, and ensures the integrity of every signed document, which is essential for legal, financial, and business-critical workflows.
If you’re handling sensitive or high-value documents, or require strict compliance standards, a digital certificate adds an extra layer of credibility and protection to your SignNow signature process.
A digital certificate also serves as proof of document integrity, confirming that no changes or tampering have occurred after signing. It assures all parties that the document remains exactly as it was at the moment of signature.
In the Signature Panel on the example below, you’ll see the status “Signed and all signatures are valid.”
This indicates that the document is authentic and has not been modified since it was signed.
