# CreateSigningMethod

### Description

This endpoint allows you to create a signing method for a user, whether it's their first or an additional one. The first signing method must always be a six-digit `PIN`, and does not require the `Signing-Method` to be passed in the header. For creating subsequent signing methods like `BIOMETRIC`/`EMERGENCY_CODE`/`PASSWORD`, include an existing valid `Signing-Method` in the request header.
