One-time password

6 things you didn't know you could do on Facebook

One-time password

Logging in from a public computer? If you don't feel comfortable typing in your password on a shared machine that might have malicious software, Facebook lets you request a temporary one by texting 'OTP' to 32665.

You'll get an eight-character passcode that works for the next 20 minutes and cannot be reused.
