Are your passwords 'unhackable'? Tips to make them more secure

Yes, it's a hassle to change your passwords and keep different ones for various accounts -- because you might not remember them.

But the Better Business Bureau says it's better to safe than sorry and has some tips to make your passwords more secure:

• Make your password long, strong and complex: Use at least 12 characters, mixed with uppercase and lowercase letters, numbers, and symbols. Avoid common words and names. 
• Don't reuse passwords used on other accounts: If a hacker gets into one account, different passwords make it harder to access your other accounts.
• Use multi-factor authentication, when available: Both your password and an additional piece of information is required to log in. The second piece could be a code sent to your phone. This protects your account even if your password is compromised.
• Consider a password manager: Most people have trouble keeping track of all their passwords. A reputable password manager can store all your passwords in one  easy-to-access place.
• Select security questions only you can answer: Don't use questions/answers available in public records or online like your zip code, mother's maiden name, birth place, color of your first car -- that can be easily guessed.
• Change passwords quickly if there is a breach: If you notice strange activity or receive notifications about a possible breach, change your password immediately.
