What is an issuing authority and how does it impact the validity of official documents?

An issuing authority is an organization or entity that has the legal authority to create and issue official documents, such as government agencies or educational institutions. The validity of official documents is impacted by the issuing authority because it determines the credibility and authenticity of the information contained in the document.
