How do people remember passwords at all? I'm not talking about these, where "rasul.23". I'm talking about these where the type is G, N, capital letter, number, square, rotifer, cat photo... Where is such a strong password? I have a four-digit password from my bank card. Why is the password more secure on a porn site? There is also this check like: "Are you 18 years old?" And the answer options are "yes" or "no". I never chose "no, I'm sure there will be: "Come on, jerk off!"
