But the truth is that it’s easier to create a long, strong, safe password than most people think. Let’s take a quick look at a few tips for making a password that will keep your account safe.
(Only those old enough to remember the Wrigley's doublemint gum commercials will get this title.)
“Multi-factor authentication” is a tech industry term for using different types of verification to get into an account. You do this daily with the 2-Step. The idea is that you use multiple things at the same time to really prove that you’re actually you. A password is one example of a factor; a fingerprint is another.

The good news is that there are some easy things you can do to protect yourself and safely shop online. Let’s take a quick look at some tips:
“Phishing” unfortunately, it's still all the rage. Attackers try to fool you into sending them money (or buying gift cards) or revealing your personal information online. The name comes from the idea of fishing: scammers send a message that acts as bait, hoping to “hook” someone.

Wi-Fi is great. Think about it, you pretty much carry an entire library and a direct line to anywhere in the world in your pocket. Nowadays many businesses offer Wi-Fi for their customers, so you can stay connected even while eating udon or waiting in line for toast.
But! That doesn’t mean it’s perfect. Using public Wi-Fi is sort of like doing, well, anything else in public: you want to be safe and not accidentally wander into trouble. Let’s talk about what you can do to protect yourself on Wi-Fi.

Apps are part of our lives now. Remember that slogan, “There’s an App for That”? Nowadays, it seems like there really is an app for everything — from games to shopping, fitness, beauty, hobbies and more. No wonder that almost 50% of all smartphone users download at least one new app a month.
Just like with any device or program, though, it’s important to choose and use your apps carefully. Some apps may be scams or contain viruses. Here’s what you can do to keep yourself safer:
