Use Temporary (One-Time) Passwords

When accessing LastPass from a public computer, you may not want to use your Master Password, because someone else may be able to access it (using a keylogger to capture your typed keys or other malware), or you may not know what kind of security is implemented on that computer. To solve this problem, LastPass provides you with the ability to generate one-time passwords (OTPs) in which each password will only work for one login session. This means that even if someone else gets access to a previously used OTP, they will not be able to use it to log on to your account.

About one-time passwords

A one-time password is something you generate after you have logged in to your account, and is something you can write down. Please be aware that one-time passwords are not sent via email or Customer Care, they are generated directly by you.

To use the one-time passwords, you generate a list of temporary passwords ahead of time, and cross them off (if they are printed or stored elsewhere) as they are used each time you log in to your account. You can also invalidate OTPs if you are concerned that they have become compromised. Please note that you can only log in with a one-time password from the one-time password login page at https://lastpass.com/otp.php.
