Migrating existing service to use Kong for auth

I’m currently working on the process of splitting up a monolith built on Laravel which is using the default Laravel authentication scheme described here. I would like to migrate this service to use Kong for authentication instead. Is this currently possible? From what I understand of Kong, I can’t simply go through my existing user table and create a consumer for each user since the hashing algorithm used by Laravel is different from that which the Kong Basic Auth plugin uses.

Does anyone have experience with such a migration? What’s the best way to go about this kind of transition without losing all of my existing user accounts? If this isn’t currently possible, what’s the best alternative course of action?
