cdn4 Im stuck in the same boat can you actually help with not having the secret pin???
That user hasn't been online since 2018. I doubt you'll get an answer from him. From the official site:
Your Secret PIN is the key that controls your coins, and your Secret Mnemonic is the only key to reset your Secret PIN in an emergency.
You should never, ever share your Secret PIN and Secret Mnemonic with anyone.
The only possible way I can think of would be by trying to crack the password. If I were you, I'd reach out to
WalletRecoveryServices. Apparently, they started supporting Block.io wallets in June 2020. They charge 20% fee (if they manage to recover the wallet).
