6. Following a phishing email -- even if you're "just curious"
If you get an email letting you know you've won $1 million for a contest you never entered, you shouldn't follow the link or provide any information. Many people know emails like this are a scam, but they still follow along for a bit. This is a huge mistake.
"Some people are curious, so they start a correspondence with the person to see if there's something there or to see what kind of a scam it is," Vogler says. "Unfortunately, any entry into who you are or where you live opens the door. It suddenly becomes really easy for them to hack into your life."
7. Failing to monitor your bank statements and credit card statements
It's surprising the amount of people who don't monitor their credit card statements or banking statements to check for fraudulent activity, Vogler says. If you keep an eye on your statements, you can catch fraud early on.
"Check all your transactions to make sure they're ones you have made. The dates and times, the merchants should all be ones you're familiar with," she says. "Look for anything that doesn't seem typical to your normal behavior and notify your bank or credit card company immediately if something doesn't check out."
8. Carrying your Social Security card or Medicare card in your purse or wallet
"You don't need to do it. It's unnecessary," Levin says. "You're totally exposed."
The elderly are already prime targets for identity thieves, and since your Medicare ID is your Social Security number, you're leaving yourself at risk by carrying either.
"You never want to have something in your purse or wallet that has your Social Security number on it," he says. "If you need to present it to a doctor or other agency one day, then carry it to the appointment and go straight home. Don't leave it in your wallet for weeks or months on end."
9. Putting too much information on social media
"Don't take a selfie with your address in the background," Levin says.
It may sound ridiculous, but some people will take a picture of their first drivers' license that displays their full name and address. Others might take a photo of their final credit card statement announcing that they've just paid off their bills -- unintentionally displaying their account number and other personal details.
"You don't take a picture saying, 'Look at my incredibly valuable new car in my front yard,' and show everyone your address," Levin says. "Your Facebook friends are not all looking out for you. Identity theft and property theft occurs even with family and friends. Why open yourself up to pain?"
10. Storing confidential info on your smartphone
Don't keep passwords, PINs or your Social Security number stored on your smartphone -- even in your email account. In other words, don't save an email called "Passwords" or "Social."
This applies to your personal information as well as the personal information of your children or family members.
"There are people out there with all good intentions who are helping their children or parents deal with a financial issue, so they store all this personal information on their phone so they'll have it handy," Levin says. "Your phone is a communication device -- not a storage device."
