Password how ? Net The easiest way to find out the secret number is to guess (considering that any number will not be devoid of 0-9), and it requires a lot of time, so hackers, even beginners, resort to virtual devices to reduce the time. The password 12345 (which is the most hacked password) means that it is discovered after 5000 attempts in less than an hour, so it is recommended to have a complex and long password of numbers, symbols, uppercase and lowercase letters, for example 1Z3c@4, and so on, up to 12 digits.
