Using credentials in a dev/preview environment

[TheUnlocked]

My app uses oauth + database sessions in production, but I would like to make it easier to test in dev/preview environments by adding a credentials provider (using an email provider isn't an option since I don't use nodemailer and I don't want to add a dependency like that if it's never going to be used in production). The issue with the credentials provider of course, is that it requires JWT, so users won't get persisted in the database.

I understand that the intent is to discourage use of the credentials provider in production, but is there a good workaround for this in dev/preview environments?
