A Word or Two about Passwords One of the simplest protections that you can have is keeping your personal and system passwords private. Change your passwords frequently. Do not use plain words as passwords combine words and numbers, or use odd spellings. Do not use names or other things associated with you hobbies, spouse's name, birthdays, etc. for passwords. Some businesses and individuals use a security algorithm to create good passwords.
Theses are quite real.
However, by using some reasonable precautions, you can overcome a number of these and still make it all work well.
