Being French myself, I would never use 'Notation' for login. Notation is a noun that translates to notation in English which means "data representation", which doesn't really mean "login", I would go with "ouverture de session" and if you need to shorten it just use "ouverture".
BTW in French "ouverture" is unrelated to musical pieces, or ballet.



>I think the French for a log is "Notation", as in noting down a fact. FYI, B, a log is like a book to store facts and times, e.g. when someone enters a club, leaves port, what happens day-to-day on a ship, etc.
