Each time, when cookies are reset on Habré, you do not just have to press OK on the login page, but also demonstrate your impressive image recognition capabilities, enter the captcha. From the first time, this is not always the case.
So I thought, why in this situation I am asked to enter it? I need a presumption of innocence - I am not a robot, at least until my behavior gives reason to suspect the opposite. Give one attempt to enter a password without captcha! I'm not mistaken, the password remembers the browser.
Update: I'll try to change the scheme a bit to make it harder for botnets who go through logins and passwords so that trying to log in to one account is not performed too often. It is necessary to allow one attempt to enter without captcha only from the computer from which the previous input was .
