Play signing keys stay with the party named in the agreement

If the account includes apps, say who keeps the app signing key. Guyi does not ask for the key in the first message and does not treat a key as proof of review.

Upload key and app signing

Google Play App Signing and the upload key are different pieces. Read what this Console shows for the named apps. Losing a key you agreed to hold is not something a new developer account repairs by itself. An empty account has no app key in the deal.

What not to promise

A handover of login, recovery, and two-factor does not move a key unless the agreement says so. Guyi does not promise that an update signed with a new key will be accepted.

Questions

Should I paste a key into Telegram first?

No. The first message is the spec. Keys, if they are in the deal, are handled after the fields match, and only as agreed.

Does an organization account change who holds the key?

No. The holder is whoever the agreement names, personal or organization.
