What does reauthorization mean?
Reauthorization means giving permission or authority again, usually after an earlier grant has expired, been suspended, or become subject to review. The term is particularly common in legal, governmental, regulatory, and administrative settings: a regulator may require reauthorization of a licence, while a legislature may approve the reauthorization of a programme or funding measure. It can also mean reaffirming that someone remains permitted to perform a regulated activity, such as operating a laboratory or practicing a profession. Unlike ordinary approval, reauthorization explicitly refers to a second or renewed act of permission and often implies a formal review, continuing conditions, or an expired prior authorization. In less formal contexts, phrases such as “approval again” or “renewal” will usually sound more natural. Nevertheless, reauthorization is useful when precision matters, especially in documents that distinguish the original grant from the decision to continue or restore it.
The act of granting permission or authority again, or a renewed formal approval of a person, project, or action.
"The licence remains in effect pending reauthorization by the regulatory board."
Primarily formal and common in legal, governmental, regulatory, and administrative contexts.
To authorize again, especially to renew or confirm permission that was previously granted.
"The committee reauthorized the transfer of the remaining funds."

The plural is used when referring to multiple separate renewals or confirmations of authorization.

Reauthorization gives yesterday's permission a fresh beginning without pretending the original approval never existed.

Where does reauthorization come from?
Reauthorization was formed within English by combining the prefix re-, meaning “again,” with authorization. Authorization itself derives from authorize, which comes from the Latin auctoritas, meaning authority or power to act, and ultimately from auctor, an author or originator. The prefixed form reflects the modern use of re- to indicate a fresh or renewed grant of authority rather than the initial authorization.
