I wanted to use LastPass authenticator together with my LastPass. I've installed the authenticator on my iphone (the device is listed among my mobile devices under the account settings). Following the instructions when setting up the multifactor authentication, I tried to scan the generated barcode but it always failed on DEVICE PAIRING FAILED. An unexpected error has occured (com.logmein.lpa.errors / -1).
Any idea how to fix it?
This error can occur when your device has notifications turned off for the LastPass Authenticator app in the device's settings. Could you double check that the phone is allowing notifications from LastPass Authenticator app?
