Here are some tips from consumer columnist Betty Lin-Fisher, compiled from experts with the U.S. PIRG Education Fund and Bankrate.com to protect yourself after the Marriott breach:

• Get credit freezes at all three nationwide credit freezes. Detailed information can be found at www.tinyurl.com/BettysBestTips for how to get a free credit freeze and other popular topics. This will prevent the thieves from opening accounts in your name.

• Change your passwords and monitor your accounts for suspicious activity. Don’t use common phrases and don’t repeat the same password at multiple sites.

• File your taxes as soon as possible to avoid tax-refund fraud.

• Sign up for your my Social Security account at www.ssa.gov/myaccount — even if you are years away from claiming Social Security before thieves do. You will need to lift your credit freeze with Equifax before you establish your Social Security online account.

• Ignore unsolicited requests for information by email, links, phone calls, pop-up windows or text messages. Marriott will notify its affected customers about its breach by email (starwoodhotels@email-marriott.com) and has said it will not ask for personal information or include attachments.

• Passport numbers were also part of the information stolen for some consumers. U.S. PIRG said at this time, unless you have physically lost your passport, the recommendation is not to re-apply for your passport. “While passport numbers can be used to create fake passports, this crime is much more difficult today due to enhanced security measures on modern passports. If we receive additional information from Marriott or federal agencies, we will update our advice.”
