Picking a good password is not as thought-free (but is twice as important) as it may seem. Whoever has your password can (in effect) "be you" anywhere on the web — posting comments, sending spam, and leaving dangerous feedback for others. Basically, such an impostor can ruin your online reputation — and possibly cause you serious financial grief.
With any online password, you should follow these common-sense rules to protect your privacy:
- Don't pick anything too obvious, such as your birthday, your first name, or your Social Security number. (Hint: If it's too easy to remember, it's probably too easy to crack.)
- Make things tough on the bad guys — combine numbers and letters and create nonsensical words.Use upper and lower cases.
- Don't give out your password to anyone — it's like giving away the keys to the front door of your house.
- If you even suspect someone has your password, immediately change it
- Change your password every few months just to be on the safe side.
