Think of a sentence that you can remember. In many cases you would not notice these attacks until it was too late. The problem with doing so is that you'll probably lose all of the recently add users and groups, and all the changed passwords for all of your users since the last backup was made. Another method is by trying hard to remember the forgotten password, or a password (using the first letter of each word) "M$8ni3y0". This method is easy enough for newbies to follow – it doesn’t require using the Recovery Console or any complicated commands. If criminals or other malicious users steal this information, they can use your name to open new credit card accounts, apply for a mortgage, or pose as you in online transactions. Your passwords should be 8 or more characters in length; 14 characters or longer.
