If someone steals your password then he can log into your account and can transfer funds to his account. Preventing such identity theft is essential. Therefore, you should use an alphanumerical password that cannot be guessed easily by others. Passwords in the name of your child, spouse, pet names etc will be easy to guess by the identity thief and hence should be avoided. You should also be aware of shoulder surfing while you enter your password. This will prevent the identity theft to some extent.
