What to do now
- Freeze your credit for free at Equifax, Experian and TransUnion, and request an IRS Identity Protection PIN at irs.gov to block fraudulent tax returns in your name.
- Contact your state DMV to ask whether your license number should be replaced, and watch for accounts opened with your ID.
- Consider reporting the exposure to the U.S. State Department if you see suspicious activity; a new passport invalidates the old number.
- Change the password on this account and on any other site where you reused it, and turn on two-factor authentication.
