# What can you do to log in?
You can re-register your device by resetting its PIN.
A MIRACL Trust registration is per device - usually a web browser or a mobile app. Users can have multiple registrations on different devices. When one device is revoked, the rest of the already registered devices are still active. If you have another registered device, you can:
- Log in with a different device, a web browser or a mobile app.
- Re-register your original device by using a QuickCode from another device with valid registration.
# What causes a device registration to be revoked?
There can be two reasons why a device registration is revoked:
- You have entered three wrong PINs: this automatically revokes your device.
- Your device Registration has been manually revoked.
