Hello JNJN
Thank you for reaching out and based on your description, what likely happened is that your Gmail address is now associated with a Microsoft account, and Copilot is automatically choosing that Microsoft account session instead of prompting you to choose a sign-in method.
In order to stop the automatic Microsoft sign-in, please try:
- Sign out of Copilot.
- Sign out of any Microsoft account in the browser.
- Clear cookies/site data for:
- copilot.com
- microsoft.com
- login.live.com
- login.microsoftonline.com
Close and reopen the browser and access Copilot again
If you're using Edge, also sign out of the Edge profile or use an InPrivate window, because Edge can automatically pass your Microsoft account to Copilot.
The steps above apply for Copilot on the web, if you're using another version of Copilot or using Copilot app, please do let me know so I can provide further support.
