What is a digital ID?
A digital ID is more commonly known as a digital certificate . To digitally sign an Office document, you must have a current (not expired) digital certificate. Digital certificates are typically issued by a certificate authority (CA), which is a trusted third-party entity that issues digital certificates for use by other parties. There are many commercial third-party certificate authorities from which you can either purchase a digital certificate or obtain a free digital certificate. Many institutions, governments, and corporations can also issue their own certificates.
A digital certificate is necessary for a digital signature because it provides the public key that can be used to validate the private key that is associated with a digital signature. Digital certificates make it possible for digital signatures to be used as a way to authenticate digital information.
How can I get my own digital ID?
If you try to digitally sign an Office document without a digital ID (digital certificate), the Get a Digital ID
