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.
Enable notifications on iOS
- On your iOS device, go to Settings→Notifications.
- Scroll down and tap to select your authenticator.
- Enable the Allow Notifications setting for this app.
Enable notifications on Android
- On your Android device, go to Settings→ Notifications.
- Scroll down to locate your authenticator.
- Toggle the switch to On to enable notifications for this app.
