Edit Character Ownership

One of my players spilled Bubbly on her laptop and she's trying to log in to Twitch on her phone. Trouble is, she doesn't remember her Twitch info. Is it possible to change ownership of a character to a different account?

Thanks!

She would have to be able to access her account and unassign the character from within a campaign. You can't claim or copy another users character.

That makes sense, or there would be multitudinous shenanigans. We got her logged in to the correct Twitch account, so it's GAME ON!
