Regenerate your QR code and reset key in the LastPass Authenticator app
If you have already set up the LastPass Authenticator app to protect your LastPass account, you can regenerate a QR code and reset the key for the LastPass Authenticator app to set it up for your LastPass account again. This might be useful if you lost your mobile device or are concerned that the security of your existing key may have been compromised. This can also be used as a means to troubleshoot multifactor authentication for your LastPass account, if needed.
Attention: If this is the first time you are setting up the LastPass Authenticator app to protect your LastPass account, view Set Up LastPass to Use the LastPass Authenticator app instead.
Important: This will require you to re-associate the LastPass Authenticator app with your LastPass account.
