Hi there @marlee0814!
Being locked out of your device can happen to even the best of us! I had this happen to me some time ago, it was easy to re-access my device. I will be happy to help!
The good news is you have the ability to re-access your device. Ensure you have access to a PC to get started. For the complete details, please click here.
Let us know if you have any additional questions. I hope you have a great week!
