Autentique

Autentique is a term most commonly encountered as the imperative form of the Portuguese verb autenticar, meaning to authenticate or verify the authenticity of something. Used in Brazilian Portuguese and other Portuguese varieties, autentique is the command form directed at a person or group to perform authentication, such as verifying a user’s identity, validating a document, or confirming data integrity.

Origin and related terms: The verb autenticar is derived from autentico, with connections to the broader family of words for authenticity. The related adjective autêntico means genuine or real, and English cognates include authentic and authentication. In many contexts, autenticar and its forms appear alongside terms like autenticidade (authenticity), autenticação (authentication), and assinatura (signature).

In practical usage, autentique appears in written or spoken instructions, particularly in security, banking, legal, or information technology contexts. For example, a software interface localized into Portuguese might display a button labeled "Autentique" to prompt the user to provide credentials. In legal or notarial settings, the concept can relate to verifying a document’s genuineness, often involving seals, signatures, or notarization.

Branding and contemporary use: Autentique is also used as a product or company name in Portuguese-speaking markets for services related to identity verification, digital signatures, or document certification. As a brand, it emphasizes trust, integrity, and the process of confirming authenticity.
