If you’re applying for a job in Maryland starting today, you can rest easy about one thing—your social media accounts.

A new law taking effect today prohibits potential employers from requesting that you give them your usernames and passwords for your social media accounts. It also makes it illegal for them to deny you employment if you refuse to do so, and protects existing employees who opt not to allow their employers access to their social media accounts.

The law—one of the few of its kind in the country—stems from a 2011 case in which an applicant for a position at the Maryland Department of Corrections was asked to turn over his Facebook log-in info, prompting the ACLU to complain that the request violated his privacy.

Of course, the new law doesn’t stop potential employers from looking through what you write on Facebook, Twitter or Tumblr that’s publicly accesible, so the usual warnings about not saying something that you wouldn’t want a future boss to see still apply.
