TODAY: Using tech to keep in touch with your kids

So the kids have headed off to college! Are you an empty nester now or just feeling blue as you look into that empty room that was once a sea of clothes and dirty dishes? Well, fret no more! We have some fun ways for you to stay connected to your kids while they are away—and you don’t have to “friend” them either!

Google + Hangouts

This is a FREE service offered by Google. Hangouts is a fun and easy way to connect with your kids that are away at school or anywhere else for that matter. All you need is a Google account. Once you sign up for Google +, you can find the Hangout frame and begin. The service allows you to choose from either doing a texting chat or a video chat. Every kid is different—some may feel much more comfortable connecting with you via text chat and others may love to see their parents or caregivers! So video chat would be a fun solution for them. You can invite up to 10 people to hangout in your chat, so if you have other kids, grandparents, aunts and uncles and they want to join, they can! It allows you to share photos and YouTube videos as well. They also have a fun effects feature where you can add silly hats, glasses and other wacky items that can make the whole experience more enjoyable for everyone.

Stay Safe on Public Wi-Fi! Here are my tips! (TODAY Show)

Ever wondered how you can stay safe while browsing the web on public Wi-Fi when at a coffee shop, airport, or other unsecured network? I set up a decoy network at a hotel in New York city and see how many people I can trick into signing on to the fake network. You need to be careful because if you connect to a decoy network, all of your passwords, credit card info, and browsing history can be captured! This is called a “man-in-the-middle” attack and it is a real threat out there!

While it can be scary, here are three easy tips to be more safe online:

1. Whenever you connect to a public Wi-Fi hotspot, make sure it’s legitimate by asking the establishment for what the correct network is.

2. Be aware of what you’re doing online. If you’re banking, shopping, working with sensitive work data, then you need to take the right precautions to be safe. You can read some of my tips for being safe online for more ideas on how to do this.

3. Try out two-step authentication. This way when you’re logging in to your accounts you need your username, password, and also a special code sent to your phone via text message. Unless a hacker can get access to your phone, your password will be useless to them!

Groupon recently sold over 100,000 coupons for an online Starbucks deal where you could get a $10 Starbucks gift card for $5. Interest was so big though, it brought the whole Groupon site down!

3. Google Street View Goes Off The Road

For a long time, Google’s Street View has allowed you to look at any street in the US where there vans have gone and photographed not only what the street itself looks like, but the business and homes surrounding it. If you’re planning a trip somewhere unfamiliar, this was a great tool to try and locate a business, see which side of the street it would be on, and even double check to see if it was actually there! Or even just take a trip down memory lane and check out a city you used to live in and see what it looks like now. But now Google is taking it off the street and into some wild locations. You can virtually hike the Grand Canyon, check out a Monastery in Tibet, and even tour around historic Italy. Hit up this link to see all of Google’s off-road Street View Collections.
