J’ai un compte prémum et ma fille ne trouve plus le siens

Hey there, 

Thanks for getting in touch about this and welcome to the Community. Hope you don't mind a reply in English as it's the official language of the Community. 

Even though this article is mainly for users who have more than one Spotify account, it might be useful for your daughter to locate hers.

On another note, if they're a member of a Premium Family/Duo plan, the owner might see their username on their Account page, under Subscription > Manage members. If the username is displayed there, they can access to their account with that info and password. 

Let us know how it goes.
