TIP: Use Two-Factor Authentication When You Can
Why not make it harder for the bad guys? Two-factor authentication lets you do just that.
All this technical term really means is that you have an extra layer of security before anyone can access one of your accounts. It means that if a scammer somehow gets hold of your password, that’s not enough info to log in.
You’ve probably used two-factor authentication many times, even if you don’t realize it. Say you are trying to log in to one of your accounts, but you must first agree to receive a code on your smartphone and send it back before you are allowed in. That’s a common example of two-factor authentication. Technology also is enabling authentication through unique physical traits, such as your fingerprint or retina.
While this technology does not shield you 100 percent from scams, it makes it much harder for criminals, who would rather devote their time to easier targets. Whatever the precise method of authentication, two-factor (or even stronger, “multiple factor”) verification gives meaningful, added protection.
Be aware that even when two-factor authentication is not required, you often may be able to turn it on. Just go to the security settings of an account, including social media, and enable it.
It always makes sense to guard against fraud.
