More and more services support a specialized app on the phone called an "authenticator," which will do that same job.
#WILDSTAR 2 STEP VERIFICATION NEW PHONE CODE#
In most cases, the extra authentication is simply a numeric code a few digits sent to your phone, which can only be used once. The problem is, we are far from ubiquity on having biometric scanners for fingerprints and retinas as that second factor. Two-factor means the system is using two of these options." Rubenking puts it, "there are three generally recognized factors for authentication: something you know (such as a password), something you have (such as a hardware token or cell phone), and something you are (such as your fingerprint). Even the White House has a campaign asking you #TurnOn2FA.Īs PCMag's lead security analyst Neil J. It's sometimes called 2FA, or used interchangeably with the terms "two-step" and "verification" depending on the marketing.
That's why many internet services, a number of which have felt the pinch of being hacked, have embraced two-factor authentication for their users. What you really need is a second factor of authentication. But what is a person afraid for their security to do? Well, you should definitely change your passwords-regularly! By sheer brute force or simple phishing, passwords are, to be honest, a pretty laughable way of authentication.
In 2014, the Heartbleed exploit left everyone's log-in information potentially up for grabs thanks to one itty-bitty piece of code.
