Setting a banking PIN

Set and verify a 4-digit PIN for money actions.

Your 4-digit banking PIN is stored as a strong one-way hash — never in plain text. Setting it requires confirming it’s you first (see Updating your profile). Verify it before money actions (provider wiring comes later).

POST BASE/v1/api/user/transaction-pin
Cookie: <session>
x-step-up-token: <token>
Content-Type: application/json

{ "pin": "4242" }

POST BASE/v1/api/user/transaction-pin/verify
Cookie: <session>
Content-Type: application/json

{ "pin": "4242" }

Never log the PIN. Failed verifies are written to the security audit log.
