Problem or use case

The use case would be to allow people with multiple ChatGPT accounts to be able to get most out of the subscriptions, often with personal and work accounts.

Proposed solution

If it can allow signing into multiple accounts of ChatGPT and let the user switch across them easily, they can make make use of multiple subscriptions if they have access without paying for a more expensive subscription.

Right now, one of the ways I'm getting around it is by switching around the auth.json file generated by codex when I am signing in. Though sometimes it forces you to re-authenticate it again.

Why this matters

This is mostly for people who are trying to make most use of their subscriptions if they have more than one account. Like for people who might have two ChatGPT accounts so they are paying $40 a month and easily take advantage of full usage given.

Smallest useful scope

A very simple way to sign in to multiple options and just switch across the accounts.
