Hey guys, hoping someone can give me some good news here.

So basically this is my situation:
My laptop motherboard died last week (rip) and on it I had a litecoin core wallet that I used as an intermediary to then move to cold storage; I never kept more than 1 LTC on it so I'm not terribly worried about the crypto itself. HOWEVER, I locked my litecoinpool account to that wallet's address so in order to unlock it I need access to the wallet to get the digital signature. While I could make a new account and redirect my miner to it, I'd just prefer not to have to login to 2 litecoinpool accounts every time I want to check out my progress, especially with one of them dead in the water. If I do have to remake a new account this would be my third time doing so, with the original account being impossible to access due to a lost authenticator.

I completely understand the security risks involved with unlocking a payment address, so I'm not expecting anyone to take me at my word. The one thing I could come up with to prove my ownership of the miner (and therefore the account which only ever had 1 miner) is my ability to modify the settings of the miner. I could overclock it or underclock it to a specific mark, or take it offline at a specific time potentially. I could also route the traffic to a new account with a pre-determined account name.

I appreciate any input!

tl;dr - can't access the old payment address anymore because laptop went kaput but I have complete access to the only miner the account has ever run. Hoping there's a way I could verify ownership given those factors.
