Facebook is one of many available social networking sites. But it is now more than social and present generation is addicted to this. Some of my friends log into Facebook 5-6 times a day, and some are always online from home.
Accessing from home is good, but what when you have to access sites from a public computer? You even don't know if the computer you are using is compromised with some harmful softwares like keylogger or something similar. There stands a great to get exposed your password.
Looking on all these things, Facebook has started One-Time Password (OTP) facility to protect its users from such tribulation.
How OTP Works?
OTP is one-time password or a temporary password for login. When you want to log into your Facebook account from a shared computer, first request Facebook an OTP, and then put your username as you do, and put the received OTP in password field. And you will be logged into your account without typing the original password.
For this, you need to have a mobile number already registered with Facebook against your account. When you need OTP, use your registered mobile to send a text with the letters otp to 32665. You will shortly receive an unique 8-character temporary password on the same mobile via SMS. Mind that this one-time password will be valid only for 20 minutes and can't be reused.
If you live outside of the US, the SMS number may be different for you depending on your country and the mobile carrier you use. Check here the one-time password numbers for all countries and supported mobile carriers. In India only four operators support this at the time.
You are free to use this service anytime you want. Specially when you feel uncomfortable entering your password information on Facebook on a public computer.
