Question

Why passwords are considered an important safety tool

Answer 1

Focus on length. The best passwords are at least 12 – 15 characters long, and can contain letters, numbers and symbols – which sounds like a lot. But remember – the important part is length! Lowercase letters on their own are just as fine as mixing it up with numbers and symbols, as long as the password is long enough. You can keep it simple by creating a short sentence that’s easy for you to remember, like summerismyfavoriteseason. For added strength, or if a website requires it, you can add numbers and symbols to the mix: Summeri$myfav0riteseason. (Bonus tips: Do NOT use common phrases from pop culture and don’t bunch up the numbers or symbols at the beginning or end of the password – spread them throughout, as demonstrated above.)
Use different passwords for accounts that contain sensitive or personally identifying information. The importance this tip can’t be emphasized enough. If you use the same password across these accounts, once it’s been cracked, ALL of your accounts become vulnerable. Just as you use different keys to protect different places, use different passwords to protect important accounts.
Password managers securely remember your passwords so you don’t have to! Most of us avoid using different passwords for different accounts because it’s just too hard to remember them all, and we know writing them down isn’t safe. Luckily, password managers - tools that store and protect passwords like banks store and protect money – can help! These tools can also create passwords that are incredibly hard to crack. All of your passwords (whether you created them yourself or the password manager did it for you) are kept within an encrypted vault, which can only be opened with a master password. The master password should be the longest, most unique password you’ve ever created, and it should not be stored by the password manager. If you’re considering this option, here are two important things to find out:
Does the company have the ability to see your stored passwords?
Does the company see or store your master password?
The most secure options will be those that answer no to both of these questions.

Use two-factor or multi-factor authentication. It sounds pretty fancy, but all it really means is instead of just entering a password to log in to your account, you will also need to enter a second piece of information. You can usually find this option in the account settings or security settings of the online service. There are a variety of options out there, and they fall within two distinct categories: “something I have” or “something I am”. Currently most services use the “something I have” kind. Here’s how it works: after entering your password, the company will immediately send a short code to something you have: an email account, a text message or voice call to your phone, oran app you have installed on your device. You then enter that code on the website and, voila! - you are able to access your account. It confirms you are who you say you are, because you verified you have the email account, cell phone, etc. that you previously connected to that account. Some emerging technologies are beginning to use the “something I am” authentication –a retina scan, a thumbprint scan, a facial recognition scan, etc.
Be wary of single sign-on. Many websites offer you the ability to use your social media or email account credentials to sign into their website, without having to create a new account. While this can be helpful because it means one less account you have to remember a username and password for, there are a number of possible risks involved with using it. When you choose to do this, you are also likely giving Facebook, Google, etc. access to more information about you than they already have, and sharing information from your social media account with the new site or service. (Remember the saying: “If the service is free, your personal information is often the price.”) A final risk to consider is that if your social site.
