Saffion says you need separate passwords for important accounts like your bank account, your primary email and anywhere you have credit card information stored. You always want your financial statements to be a separate password,” he said. “Don’t answer security questions with things people can guess about you.”

Saffion says if the question is what is the name of your first pet, answer something else like the name of your first car. Passwords and security questions become more secure if it doesn’t apply to the question being asked.
