# Manually update the ZivverAccountKey

## Introduction

Some situations may require you to update the `ZivverAccountKey` in Zivver — for example, when migrating from one source system for account provisioning to another. This manual describes how to update the `ZivverAccountKey` for users using the Zivver Synctool. It is currently not possible to update the `ZivverAccountKey` with Zivver Cloud Sync.
