If you aren't applying for credit (like a mortgage or new credit card) in the near future, consider putting a freeze on your credit. This will make it different for someone to sign up for credit using your information.
Reach out to the three credit agencies (Experian, TransUnion, Equifax) and put a freeze on your credit. Equifax is offering to waive the freeze fee for the next 30 days.
What does this do? It means no one can look at your credit or apply for credit using your credentials until the freeze is lifted. This won't affect the accounts you already have open, so you'll still be able to use your credit card and make payments on any loans you have.
Freezing your credit does not affect your credit score, but it costs money to un-freeze your credit (usually between $30-$50.)
