For security reasons, unlocking the payout setup can only be done by providing a signature from one of the wallets used in the payout setup to our support team. We will then verify the signature belongs to your registered wallet and unlock the payout setup. In other words, it is not possible for a user to unlock the payout setup by themselves.

Thanks to Payout Setup Lock, even if your Slush Pool account is compromised, there is no way for the hacker to steal your mining rewards. However, since we do not require our miners to verify their personal identity in order to use a mining account, the only way to safely ensure the integrity of the request to unlock a reward split is by requiring a wallet signature. 

If you want to make your account more secure without locking the reward split (or simply in general), we strongly recommend that you set up 2-Factor Authentication (2FA)
