uwierzytelniajcych

Uwierzytelniających is a Polish present participle form derived from uwierzytelniać, meaning to authenticate. It functions as an adjective or nominal modifier that designates agents carrying out authentication. The term is most common in formal or technical Polish, including security policies, standards, and academic writing. It is typically used in genitive plural, as in podmioty uwierzytelniających użytkowników, meaning “entities that authenticate users,” but can appear in other cases depending on the sentence structure.

In IT and security contexts, uwierzytelniających identifies the actors responsible for verifying credentials, such as passwords, tokens, or biometric data. These actors are distinct from the authentication process itself (uwierzytelnianie) and from authorization, which governs access after identity is confirmed. Common phrases include mechanizmy uwierzytelniających danych (mechanisms of authenticating data) and strony uwierzytelniających użytkowników (parties that authenticate users).

Grammatical note: uwierzytelniających is a participial form, often functioning as an attribute for plural subjects or objects. It is related to the verb uwierzytelniać (to authenticate) and to the noun uwierzytelnianie (the act or process of authentication). While uwierzytelniających describes the doers of authentication, the process itself is typically referred to with uwierzytelnianie or uwierzytelnienie in Polish.
