bona fides

Evidence of legitimacy

Bona fides is evidence of good faith, authenticity, or legitimate credentials.

From Latin meaning "good faith," it typically refers to proof that someone is who they claim to be or has the qualifications they profess: The reporter verified her bona fides before granting the interview.

Unlike most Latin plurals, bona fides functions as singular in English: His bona fides is beyond question.
