One-time Password

If you are using an untrusted public computer and need to access your LastPass data but are hesitant to do so because of potential keyloggers, LastPass provides One-Time Passwords (OTPs) as one option for securely accessing your account.

A one-time password (OTP) is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid a number of shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two-factor authentication by ensuring that the one-time password requires access to something a person has (such as a small keyring fob device with the OTP calculator built into it, or a smart card or specific cell phone) as well as something a person knows (such as a PIN).
