# Sign in with your Google account

You need a Google account to use GPT for Sheets – Autosheet.

When you launch the GPT for Sheets – Autosheet add-on:

- The add-on works with the Google account you are currently using.
- In Autosheet, you need to sign in again when you first use the [bulk tools](https://autosheet.com/docs/gpt-for-sheets/bulk-tools). This is to grant a required additional permission.

If you have multiple Google accounts, such as a personal account and a work account, you can [switch between them](https://autosheet.com/docs/gpt-for-sheets/setup/sign-in/switch-to-another-google-account) to ensure you are using the correct account in Autosheet.
