My professor used the word authentification in a lecture. I have always used authentication. Is it a real word or is authentication the correct term?

  • Several other languages use the form with "fi" and even though the "authentication" is correct in english, "authentification" suggests itself. Also "Authentification" in this exact form comes from french. –  Qwerty May 9 '17 at 9:27

Authentication is the preferred form in English. The variant authentification is acceptable, but less common—it’s often used by non-native speakers who aren’t aware that it’s less idiomatic in English, because authentification (or an analogue) is the correct form (or at least widely accepted) in many eastern & western European languages:

  • Azerbaijani: autentifikasiyası
  • Basque: autentifikazio
  • Belarusian: аўтэнтыфікацыя (autentyfikatsyja)
  • Bosnian: autentifikacija
  • Corsican: autentificazione
  • Czech: autentifikace
  • Danish: autentificering
  • Dutch: autenti(fi)catie
  • French: authentification
  • German: Authenti(fi)kation
  • Haitian: otantifikasyon
  • Kazakh: аутентификация (autyentifikatsiya)
  • Latvian: autentifikācija
  • Lithuanian: autentifikavimas
  • Luxembourgish: authentifikatioun
  • Romanian: autentificare
  • Russian: аутентификация (autyentifikatsiya)
  • Spanish: autenti(fi)cación
  • hi air Nike orange Fly teal BG Basketball Trainers electric top tropical 684936 Jordan 3 black pink fusion Super 625 Sneakers Shoes Ukrainian: автентифікація (avtyentifikatsiya)
  • Uzbek: autentifikatsiya

(Source: Google Translate—transliterations from Cyrillic are a best effort and may not be standard/accurate for all languages.)

According to the Online Etymology Dictionary and Wikipedia, authentication was the original form, via Latin authenticare, from Greek αὐθεντικός (authentikos), from αὐθέντης (authentis) “author” + -ικός (-ikos) “relating to”—cf. Latin -ic(us).

According to the Oxford English Dictionary, the change to authentification seems to have happened in the mid-18th century—in English at least. It likely arose by analogy with similar words such as personification, modification, 684936 Trainers Basketball teal hi 625 Jordan top air 3 Fly fusion Sneakers Super BG Nike black pink tropical electric Shoes orange ratification, unification, &c., which all include the Latin element -fic-, from ficare, the combining form of facere, “to make”.

Authentification is a French word. After a bit on research on its origin, it would seem that the word is actually composed of three parts :

  • authentique (authentic)
  • fic → faire (to do)
  • ation → action
