Composition

A PIN can be used as an additional verification method for child addresses. To process certain tasks (i.e., withdrawal) with PIN-enabled child addresses, the correct PIN must be entered to proceed with the task.

PINs can be composed of any character, including numbers. Octet encrypts and securely stores these PINs to ensure their protection

Recovery PIN

It is used to control (modify or delete) the PIN of the child address, and it must be entered when generating the PIN. Clients may use Recovery PINs in many ways, depending on their PIN operation policy.

1. Use as Master PIN

When the client enters the Recovery PIN, it can be used as a Master PIN. In this case, when an end user loses the PIN or wants to change, the client can handle that with the Master PIN, which enables efficient CS.

2. Use as a secondary PIN

When the end user enters the Recovery PIN as well, it can be used as a secondary PIN. In this case, when an end user loses the PIN or wants to change it, the end user must enter the Recovery PIN by the user. No one except the end user may access the asset. However, when the end user loses the secondary PIN, the PIN cannot be changed or deleted.
