When making a new password, you can use SecurityStats.com for guidelines and to “test” your password.
Use a mix of upper case and lower case letters, symbols, letters, and numbers. Don’t use a word in the dictionary. (Password crackers sometimes use word lists from a dictionary)
Don’t use a password you use for other accounts.
For wordpress, I would recommend you avoid using your accountname as your nickname. My friend told me his ex-girlfriend hijacked his email, blog, and AIM screenname. Don’t share your password with anyone… especially your girlfriend. -.-
With thanks! Valuable information!
