Unique to you.

Use your unique digital identity to easily validate your credentials and authorize your signature when you digitally sign.

Easy to validate.

Digital signature validation requires renewal -the signed document and digital signature are designed to be revalidated for at least 10 years.

Why are digital signatures secure?

A digital signature is a specific type of signature that is backed by a digital certificate, providing proof of your identity. Digital signatures are recognized as being a more secure type of e-signature because they’re cryptographically bound to the signed document and can be verified. When you use a digital certificate obtained from a trusted third party to e-sign, the resulting digital signature is virtually impossible to spoof. It also provides powerful evidence of signer identity, that the signed document was not altered, and that the signatures are valid.

What is a digital identity?

A digital identity (or digital ID) is like an electronic passport. It provides strong evidence that you are who you say you are when e-signing a document. Each digital ID is issued by a trusted third party, such as a bank or government, after thoroughly verifying your identity.


Using a digital ID to authenticate your identity when e-signing a document strongly affirms that you have agreed to the terms and have authorized your e-signature on a specific document.
