Yes, I know that there is already a thread about authentification here but anyway, in German we differ between the active process of authenticating our selves and the passive process of being authenticated.
The active part would be: we know something or we own something what we use to authenticate ourselfe to the server. The passive part would be: the server validates the information and authenticates the user as an authentic user.
Any reason, why the different meanings are compressed into one word?
