Pinterest also has two factor authentication

san francisco - Pinterest users can now better protect their account. The site has entered two-factor authentication. After completing the password, Pinterest sends an SMS with a code to the user's phone to prevent strangers logging in. It is also possible to use an authentication app like Authy.

Pinterest also shows which devices are logged in. If there is an unknown device between them, a stranger is likely to log in. That device can be easily quit from the Pinterest account. Pinterest will also email users when they log in from an unknown device.
