(CNN) -- Facebook users will be able to log off the site from their cell phone and get a temporary password to use on public computers under new security changes.
The updates, announced Tuesday on Facebook's official blog, come as the social networking juggernaut observes National Cyber Security Awareness Month.
"From our standpoint, safety and security is a core part of Facebook and a core part of the user experience," Joe Sullivan, Facebook's chief security officer, told CNN in a telephone interview. "It's a core part of the ways we innovate as a company".
The "one-time passwords" will be available to users when they're on computers at libraries, hotels or other public places where they feel their regular password might be compromised.
Users can now text "otp" to 32665 on their mobile phones. They'll immediately get a password that can be used only once and expires in 20 minutes.
The feature is being rolled out gradually and should be available to all Facebook members in the next few weeks, according to the blog.
A new tweak also will let users find out if they're logged on to Facebook on another computer.
"Have you ever borrowed a friend's phone to use Facebook and then forgotten to log out before you handed it back?" read a blog post from last month promoting the pending feature. "Maybe you logged in from a public computer, but accidentally walked away with your Facebook session still active".
Users will now be able to go to their Account Settings page, find a list of all the computers on which they are currently logged in and shut down the unauthorized log-ins.
That feature is already available to all users.
