Secure Passwords

Many people who use a Linux Operating System believe that it is by definition a secure system and that they are in no danger. I was once told that Linux is like a room with all the doors and windows closed and locked. I have also been told that the only truly secure computer is one that is disconnected from the Internet, turned off, unplugged and battery removed (for laptops), and placed back in its box on the top shelf of the hall closet. The truth is probably some where in between.

There are things that a Linux user can do to make his/her computer more secure. The greatest danger and thus the first line of defense for the individual computer is the password. So how do you make your password effective? Obviously everyone is aware that passwords such as password or 123456 are not very good but not very many of us want to use a 64 character randomly generated combination of letters and numbers every time that we log on to our personal computer. So what makes a good one.
1. Avoid dictionary words or their derivatives such as pa$$w0rd.
2. Include at least a couple lower case letters, capital letters, numbers, and special characters.
3. Use different passwords for different accounts.
4. Change your passwords every six months
5. Avoid dates (birthdays & anniversaries).
6. Avoid personal data.
7. Should be at least 15 characters long.

Does all of this guarantee that your password is strong and will never be compromised. Well, no. However, it makes it extremely difficult to hack even with some of the downloaded password crackers. There are too many easier passwords out there, so why would they mess with a hard one. Just don't let it be you.

Consider a password Safe like KeePassX Free. You only need one password to unlock the safe. Then you can generate long secure passwords and just copy and paste where ever you need a password with each site using a different password so that if someone gets one of your passwords the others are still safe. use several computers? no problem keep the database on a usb or file sync service since the data base is encrypted. Remember your user info does not need to be your name either. Hi my user name is VayHictOpul73 my password is ************************************************** have fun.
