Hi there @Heyyou
Thank you so much for your first post to our community forums and welcome to the team! It's great to have you here!
I'm so sorry to hear that you have lost this security key! I'd be more than happy to look into this further with you via a PM.
I will pop one across now, please keep an eye out for the purple envelope in the top right corner of your screen alerting you to a new message.
Thanks again.
