Copilot Web-wrapper app on macOS causing identity conflict, missing history, and repeated credential errors Case Number: 7107631998

Hello, I’m requesting help escalating an identity-related issue involving Copilot on macOS. This is not a Copilot M365 problem — it appears to be an identity token conflict caused by a second Copilot login pathway on macOS.

What happened

A Copilot app icon appeared in my macOS Applications folder. When opened, it launched the browser-based Copilot web experience, not Copilot M365. This indicates it was a browser-installed web-wrapper (PWA-style), not the native macOS Copilot app.

This web-wrapper authenticated using a different Microsoft account identity than my Copilot M365 subscription. As soon as this happened:

• My Copilot M365 history and library remained intact
• My browser-based Copilot history and library disappeared
• The web-wrapper began generating repeated credential pop-ups
• The browser version showed no history
• Copilot M365 continued working normally
• The corrupted identity token caused persistent “The credential is invalid” errors

• Tag: 965ya
• Code: 0

Root cause

The macOS web-wrapper Copilot app authenticated using a different Microsoft account token than Copilot M365. This created a cross-identity conflict between:

• Copilot M365 (correct identity)
• Copilot Web-wrapper (incorrect identity, corrupted token)

This conflict caused repeated authentication attempts and degraded performance.

Steps I’ve already taken

• Removed the web-wrapper Copilot app from macOS Applications
• Cleared browser identity and cache
• Signed back into Copilot using my Microsoft 365 account
• Verified Copilot M365 history and library are intact
• Issue continues

Request

Please escalate this case to the Identity & Token Integrity engineering team. This issue involves:

• Cross-identity token collision
• Corrupted browser/PWA authentication token
• Incorrect identity routing between Copilot Web and Copilot M365
• Repeated credential invalidation loops

This is not a Copilot M365 issue — it is an identity-layer issue affecting Copilot Web on macOS.
