How do I set up additional security options for LastPass?
You can set up additional security options to further protect your LastPass account.
Security Option #1: Add a security email address for alerts
Security Option #2: Generate temporary One Time Passwords
One-time passwords (OTPs) can be used if you want to access LastPass from a public computer and do not want to enter your master password because someone else may be able to access it (using a keylogger to capture your typed keys or other malware). They are also handy if you need to access your LastPass vault but you do not know what kind of security is implemented on the computer you are going to use.
To use the One Time Passwords, you generate a list of temporary passwords ahead of time, and cross them off 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 One Time Passwords do not replace your Master Password. Additionally, if you log in with a One Time Password, you will not be able to export your LastPass vault data.
