ChatGPT now lets you stay signed in to 2 accounts and switch without logging out
The ChatGPT help page says account switching works on ChatGPT web and is rolling out on iOS and Android. Only one account is active at a time: chats, memory, files and settings follow the selected account, and switching does not move chats or share a subscription. A second account costs nothing to create and starts on the Free plan. Organizations may turn it off for managed workspaces.
