Poolin users may meet cases of creating one wrong or undesired sub-account and hope to delete or modify it to another one, but cannot find the option of delete/modify sub-account in both Poolin website and and application.
For security concerns, we do not support delete or modify sub-account. If you want to delete sub-account, you can try the function "hide the sub-account". To hide sub-account, please do as follows:
1) visit www.poolin.com and login
2) click sub-account manage and then you will see the following page
3) put your mouse on the sub-account that you hope to hide and then you will see an "eye" button on the left
4) click the button and then the sub-account is hidden
1）Open Poolin App, click dashboard
2）Click up left button
4）Choose the sub-account you'd like to hide and click ... then you will see the option of hide sub-account
5）Click and then the sub-account is hidden
Now let's going back to the problem of why delete or modify sub-account is not allowed.
Miners are connected to a pool by setting mining address, worker (sub-account.minerID) and password. The sub-account you use is the only identification to figure out who the miners are mining for. If you mistakenly set a wrong sub-account, you may be mining for other customers.
To ensure the security of customers' mining profit, sub-account will exist as long as it is created and no operation can be done to an existing sub-account, for example operations like modify, or delete.
