One API key for multiple users

[brisk pond]

If one API Key is used in an app with multiple users, can ChatGPT have independent conversations with the multiple users while using the same API key? I don't want conversations to bleed into eachother. If the conversations will bleed into eachother, then is there a way to create a new key for each user without having them log into OpenAI to create an account? Thank you for your help !

The models have no memory of past requests, all relevant information must be supplied via the conversation. You have to handle conversations for each user by the sending the whole chat history or using embeddings to search the conversation history.
