In other cases, users can use smartphone apps as a second-factor device, so they can confirm logins with a single tap. For example, many banks use SMS-based 2FA, and text you a numeric code to enter to access your account after you’ve entered your password. In a 2FA transaction, after entering your username and password, you’re prompted to confirm the access request through a different medium. Two-factor authentication creates another safeguard beyond your password. Thankfully, the web security industry has created a new standard that anyone can use to protect their online accounts from unwanted intrusions: two-factor authentication (often referred to as 2FA). Sophisticated attacks and unexpected data breaches are so commonplace now that if you want to stay safe, you’ll need to take additional measures.
Unfortunately, a password is no longer enough. As we move more and more of our personal information into the cloud for convenience, it becomes increasingly important to make sure that our data is secure.
