"Authentification"

THIS WORD DOES NOT EXIST.

Seriously, Google it. "Authentification" is most likely a combination of authentication and identification. It is not an actual word and there is no form of the word authentication that includes an f anywhere. Think you read it somewhere? Either the person who wrote it was an idiot or YOU ARE PRONOUNCING IT WRONG. Au-then-ti-cation. THERE IS NO F!
