Why do I get a message, "Device Pairing Failed. An unexpected error has occurred" when pairing my mobile device?
This error message can occur if your mobile device's settings do not allow for notifications to be sent to the authenticator app when setting up Multifactor Authentication for your LastPass account. This issue has occurred specifically for authenticator apps that support push notifications (for example, LastPass Authenticator, Microsoft Authenticator, etc.).
To resolve this error, you must enable notifications for your authenticator app on your mobile device, then resume setting up Multifactor Authentication.
