# Sign in and use the same account

Use the correct sign-in method across devices and investigate missing chats, creations or purchases without creating duplicate accounts.

Read this guide in: [English](https://book.rochat.ai/rochat_book_en/sign-in-and-sync) · [繁體中文](https://book.rochat.ai/rochat_book_zh/sign-in-and-sync) · [日本語](https://book.rochat.ai/rochat_book_ja/sign-in-and-sync) · [Español](https://book.rochat.ai/rochat_book_es/sign-in-and-sync) · [한국어](https://book.rochat.ai/rochat_book_kor/sign-in-and-sync)

When chats or purchases appear to be missing, first check which Rochat account is signed in. Using the same device or a similar email address does not by itself prove that two sign-in sessions belong to the same account.

## Sign in on another device

1. On the device that has your content, note your Rochat account identifier and the sign-in method you used.
2. Open the official Rochat Web app or mobile app on the other device.
3. Choose the same sign-in method and the same provider account. If you originally chose Apple or Google, start with that same option.
4. Compare your Rochat identifier before checking chats, creations or membership.
5. Open the existing item rather than creating a new conversation or duplicate work.

With Sign in with Apple, a private relay email may differ from your usual email. Use the original Apple Account and sign-in route; typing your everyday email into another route may not reach the account you expect. Apple explains how to [check the apps and information associated with Sign in with Apple](https://support.apple.com/en-us/102571).

## If a verification code does not arrive

Check the destination displayed, country or region prefix where relevant, spam filtering for email, and any resend timer. Request a new code only after the interface permits it. Enter the most recent code and never send it to support or another person.

## If content is still missing

Record the Rochat identifier on each device, the affected item link, the last time you saw it and the platform versions. A missing purchase also needs the original store and transaction identifier. Contact [Get official Rochat support](https://book.rochat.ai/rochat_book_en/about-rochat/faq) with those details.

Do not delete an account, buy the same item again or assume two accounts can be merged as a troubleshooting step. For a subscription that is charged but not recognized, use [Manage subscriptions and refunds](https://book.rochat.ai/rochat_book_en/about-rochat/faq/subscription-faq).
