Another example of two factor authentication is with a safe deposit box in a bank. So even if you’ve never heard the term “two factor authentication” you have almost certainly been using it for a while. Each of these, the card and the PIN, are authentication factors. When you use a bank cash card at an automated teller machine (ATM) you must provide the machine with both your physical card (something you have) and with your PIN (something you know). But for the sake of simplicity, I’m going to stick with just “knowing your password”. So to be more precise when talking about logging into a site, I really should have said: “your ability to correctly enter your site password based on some knowledge in your head (your 1Password Master Password)” is an authentication factor, instead of “knowing your password” for the site. I naturally use the 1Password Strong Password Generator to create most of my passwords, which means I not only don’t know those passwords, I haven’t even seen most of them. Of course, if you use a password manager like 1Password, you probably don’t know most of your saved passwords. Your knowledge of your password is an authentication factor. When you log into our forums with your username and password, knowing your password proves that you are the same person who set up the account. What is Multi-factor Authentication?īefore we descend into the buzzwords that this topic requires, let me first say that “authentication” means proving who you are to some system. Ultimately, the question boils down to two kinds of data security risk: threats to confidentiality versus threats to availability. “Why doesn’t 1Password offer two factor authentication?” That is a question we face regularly, and one we often ask of ourselves. Teams can also use Duo’s authentication app as an extra layer of protection for employee accounts. You can now protect your 1Password account with two-factor authentication, using an app like Authy or a security key. Editor’s note: This blog post was written in 2011.
