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

The document issuing authority is the organization or entity responsible for creating and issuing official documents. The authority's credibility and reputation can impact the validity of the documents they issue. If the issuing authority is recognized and trustworthy, the document is more likely to be considered valid and reliable. Conversely, if the authority is not reputable, the document's validity may be questioned.
