Authentication options on behalf of a user

Welcome to the forum.

Bring your own key isn’t supported by OpenAI as far as I know…

OpenAI's "bring your own key" policy

I’m interested in potentially building an application where users can enter their own OpenAI API key into my application and use the service that way. This key may be stored in a database by my application. I’m wondering what is the OpenAI policy on letting users bring their own key? Is there any commercialization challenges and restrictions in doing so? Maybe guidelines on best practices which could be helpful I could check out? Thank you!
