We rely on portable wi-fi hubs more than ever before. It’s the epitome of convenience to take your connection with you, even in the most unconnected locales. But it’s beyond frustrating to find that the bandwidth you pay for each month is getting siphoned off by wi-fi leeches.

That’s especially true if, like most people, your hotspot service plan limits the amount of data you can use. So how do you keep out the freeloaders and protect your information? Verizon

1. Use WPA2 encryption.Some hotspot devices come equipped with WEP, which is necessary if you’re using older devices, but if it’s at all possible, you need to be on the latest encryption mode, because that’s going to be the most secure option.

2. Use your own Pre-shared key. The one that came in the box is not strong or secure enough, so create your own. Make it long, varied, and not something you’d find in a thesaurus. Change it from time to time.

3. Don’t overshare. Exposing your pre-shared key and your connection to others, even people you trust, can end up putting your information into the wrong hands, eventually. If you do decide to share, make sure to change your key again as soon as you’re done.
