Good evening ! There is such a difficulty or problem ....
1) There is a site, no matter which site is "Z", where you can enter the password endlessly, that is, to sort out the password, and you need ways to achieve this goal.
2) The same site is "Z", now the task, on the contrary, needs brute-force protection. I thought that after 3 wrong ones, a query pops up with a captcha or a 2 + 2 type puzzle? .
But the main question is to find out what types there are implementations or simpler methods for task number 1.
