Almost all working fine with sensors and web interface and i want to put an simple authentification with login/password to access but the simple exemples i try doesn't work.
I attached my sketch below, if someone could give me a little help please.

That code does something that you failed to describe. You want it to do something else. "i want to put an simple authentification with login/password to access" isn't a good requirement statement.
