# 設備遺失或損毀了如何安全處理？

首先需要區分該裝置是否儲存了Cregis 錢包的MPC分片，如果沒有分片，則無需特別處理。

如果是存有MPC分片的裝置遺失，為了防止遺失的手機被他人使用，在以下各種場景下分別的處理辦法：

## 1. 錢包的創建者的設備損毀或遺失

如果該錢包的創建者有多台設備具有該錢包分片，則可以通過其他正常的設備進行授權，操作流程可參考此[連結](/cregis-wallet-guide/zh-tw/wallet_and_transaction/shard.md)。

如對不可用設備上的分片有安全疑慮，可直接在其他設備上，對該有問題的設備的分片進行刪除操作，操作流程可參考此[連結](/cregis-wallet-guide/zh-tw/wallet_and_transaction/shard.md)。

如果該錢包的創建者只有一台設備且該設備出現問題，此時可以考慮重置分片功能，輸入助記詞，對該錢包所有的分片進行重置，所有分片更新，且非錢包創建者需要重新授權分片，操作流程可參考此[連結](/cregis-wallet-guide/zh-tw/wallet_and_transaction/shard.md)。

## **2.** 非錢包的創建者的設備損壞或遺失

如您擔心對應的裝置存有分片會對資產產生潛在的風險，可以透過分片管理功能，錢包的創建者將指定裝置的分片刪除，則對應的分片即失效。

如該成員有新設備需要繼續使用，則透過常規的分片授權功能即可完成分片的繼續使用，操作流程可參考此[連結](/cregis-wallet-guide/zh-tw/wallet_and_transaction/shard.md)。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.cregis.com/cregis-wallet-guide/zh-tw/faq/security/she-bei-yi-shi-huo-sun-hui-le-ru-he-an-quan-chu-li.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
