The rollout of a big chunk of the Affordable Healthcare act has internet security experts on edge.
They're expecting criminals to also have a rollout of their own - new scams.
Bob Sullivan is an author and internet security expert. "This might be the opportunity of the decade for the phishers."
They're expected to dress up emails to look legitimate and entice you to click on links that lead only to no-good.
Wade Baker of Verizon said, "If you get an email that says "do this or you're gonna lose your benefits", there's a pretty decent chance you're gonna click on that and look into it."
Internet security experts say the crooks plan to cash in on the confusion of the Affordable Healthcare Act, also known as Obamacare - as well as the process.
"I don't know how the legitimate exchanges will be able to distinguish themselves and their emails from the phishing emails."
If ever there's a time to be vigilant, it's now.
"We need to be suspicious of it. if it's unsolicited, comes from someone you don't know, that should be an automatic flag. if it's poorly written, that's another flag"
"Another thing that will help people..no matter how annoying it might be is: everytime you go to one of these websites, go up to that address bar and type it manually and re-login that way. don't use any links sent out by anybody."
Security experts also say don't be in a hurry. People who are eligible to buy health insurance through the exchanges have until next April to sign up.
A few other tips to keep in mind:
The insurance marketplaces are only for people who don't already have health insurance - meaning most people don't have to do anything.
The government is not calling, or sending emails, or knocking on people's doors to sign them up for health insurance under the affordable care act.
