Your password is the key to your data and should be nearly impossible for someone to figure out. Choosing a secure password is paramount for keeping your data secure.
There are specific things you should avoid when choosing a password, including the following:
Remember, it is part of your responsibility to create a strong password. For maximum security, always take extra precautions when creating a password so that sophisticated crackers cannot acquire your personal information.
A strong password is one that you change on a regular basis. A good practice is to change your password at least every three to six months.
There are several reasons for this. First, passwords are often stolen without the knowledge of the victim, and stolen passwords often aren't used immediately. They're collected, sold to organized crime, rebundled and resold, and left unused for some time. Even if you're not aware your password was stolen, if you change it periodically you may change it before a thief has an opportunity to use it. Second, computers are always getting faster. It's possible to guess your password through sheer persistent computer effort. With current technology, this takes months if you have a strong password. If you change your password every six months, any brute force attack that takes longer is ineffective.
