It's impossible to remember 200 passwords

Most people can’t remember a dozen passwords, let alone hundreds. How do they cope? Typically, they’ll pick one or more easy-to-remember passwords for sites they don’t consider critical. So, the sequence might be: Password, Pa55word, Passw0rd, and finally Password! Users resort to this “tactic” when they’re forced to change their passwords regularly, such as every 90 days. “Decades ago, we were concerned about a criminal trying to get into an account,” Ross explained. “If they realized that people were using such simple passwords, they might continue to try to break in with brute force attacks.”

The level of protection against such attacks provides for a certain number of attempts that are given to enter the site. If the user enters an incorrect password three times, then access to the site is blocked. It should be noted that some sites allow more than three attempts or do not limit them at all, but such sites are a minority. Such an insignificant number of unsuccessful attempts is provided so that the user can remember his password and filter out hacker attacks aimed at selecting passwords.

The ease of cracking varies greatly depending on chile mobile database complexity of the password. An experienced attacker armed with sophisticated software can crack a short password in a few minutes by selecting words from a set of popular password words. A password of 99 characters, consisting entirely of random characters, is almost impossible to crack. But if you reuse one password, making small changes to it, it can be cracked much faster and easier. Once the attacker knows the specific character strings in the password, his software will significantly reduce the variations of words required to guess the password.
