I don't know if I am in the correct forum but I have installed the Authenticator app on my Windows Phone and it is registered under the lastpass website and in my Vault.
I use SMS messages for Facebook so no one can log in without my phone but when I went to log in, LastPass asked me to "Enable" the Authenticator for Facebook but when I went to the app on my phone, there was no 6-digit code.
I really have no idea what this is for or how it is meant to save me time because I thought all my 6-digit codes were meant to come through the one app, rather than as SMS messages.
In LastPass Authenticator, I can see a field for issuer, Email and User Secret but there is no documentation about what these fields are for so while Facebook have not provided a QR code I have no idea what to enter.
Hope someone can help.
