You can create your own electronic signature and apply it to all sorts of documents and email messages. The thing to remember with this type of signature is that it is not a secure signature. Anyone can copy and paste your e-signature into a new document or email message. While it does add a level of professionalism to your documents and emails, it is not the best solution when working with important documents, which need to be signed and authenticated.
Important Business Documents Require a Digital Signature Not an Electronic Signature
Instead of using your electronic signature on important business documents, you will want to use a digital signature. A digital signature is an encrypted signature which is secure. Using a digital signature, would be like signing paper documents, with witnesses and a notary present. Your digital signature cannot be copied, altered or modified. As a result, it is considered authentic, when others open documents, you have signed.
