Losing my phone that has the LastPass Authenticator app

[NemoUI]

If I lose the phone on which I have the LastPass Authenticator app, how do I access my LastPass account, and how do I prevent someone else from using the phone to access my account?

Thanks for your assistance.

Hi @NemoUI, welcome to the community.

LastPass Authenticator has a cloud back up feature that you can enable and use to back up your 2FA sites, if you lose your phone you can install the LastPass app and Authenticator app and then restore the back up to your new device. 

As for your lost phone, you would want to make sure the LastPass and Authenticator apps are set to end sessions automatically after an appropriate amount of time and require you re-enter your master password or some other form of authentication before they open. You would also be able to sign into your account and kill all sessions so that all devices require you sign back in again to access your vault.
