Do I need to sign in to Copilot before December 31 to keep my chats?

Microsoft Support says personal Copilot users must sign in to the updated Copilot app by December 31, 2026 to keep eligible chats — anything not migrated will be permanently deleted after that date. Here is what moves with you, which features retire, and the five steps to protect your chats this week.

You open Copilot, find that recipe, work note or long chat you saved months ago, and would hate to lose it over a missed deadline.Short answer: Yes — if you use Copilot with a personal account and want to keep your chats. Microsoft Support says to sign in to the updated Copilot app by December 31, 2026 to preserve eligible chats and content. Anything not migrated will be permanently deleted after that date.Why it matters: Microsoft is folding Copilot into one updated app across personal, work and school accounts, though those accounts stay separate.

Most chats and content move with you when you sign in with the same account, and files from the standalone app move to OneDrive. Some features are retiring and do not carry forward, including Group Chat, Podcasts and Deep Research. Separately, Copilot leaves Samsung and LG TVs on December 1, 2026, but stays on web, desktop and mobile.

If you used Copilot Tasks on a personal account, you move to Cowork Preview with scheduled tasks switched off, so they need turning back on.How to keep your chats:1. Open the updated Copilot app, or Copilot on the web, and sign in with the same personal Microsoft, Google or Apple account you used before — and do it before December 31.2. Check your important chats are actually there once you are signed in.3.

Copy anything in Group Chats, Podcasts or Deep Research into a document or notes app, because those features do not carry forward.4. If you used Copilot Tasks, find your schedules in Cowork Preview and turn them back on.5. On a Samsung or LG TV, simply switch to Copilot on your phone or computer after December 1.Common mistake: Signing in with a different email creates an empty-looking account.

The usual story is not that your chats are gone — you are just signed in to the wrong account.Ad’s take: Two minutes signing in now beats losing a year of saved chats over one missed date. Set a reminder this week, sign in, check one old chat is there, and be done with it.
