Facebook provides a number of ways to help you protect yourself and your account, and today we are announcing new features to help make your experience on Facebook more secure.
First, we're launching one-time passwords to make it safer to use public computers in places like hotels, cafes or airports. If you have any concerns about security of the computer you're using while accessing Facebook, we can text you a one-time password to use instead of your regular password.
Simply text "otp" to 32665 on your mobile phone, and you'll immediately... receive a password that can be used only once and expires in 20 minutes. In order to access this feature, you'll need a mobile phone number in your account. We're rolling this out gradually, and it should be available to everyone in the coming weeks.
Second, the ability
to sign out of Facebook remotely is now available to everyone.
These session controls can be useful if you log into Facebook from a
friend's phone or computer and then forget to sign out. From your Account Settings,
you can check if you're still logged in on other devices and remotely
log out. Under the Account Security section of your
Account Settings page you'll see all of your active sessions, along with
information about each session. In the unlikely event that someone
accesses your account without your permission, you can also shut down
the unauthorized login before resetting your password and taking other
steps to secure your account and computer. Lastly,
when people log in to Facebook we will regularly prompt them to keep
their security information updated. If you ever lose access to your
account, having this information helps us verify who you are and get you
back into your account quickly. You don't have to wait
for us to prompt you; you can update your security information at any
time from this
page.
