I think I know what you’re asking here, and I’ve seen this same ask appear in many different places across the Auth0 community forums. Many people seem to be asking for a user-based API key system - which Auth0 does not currently have.
They have made a public issue to vote on for this feature, but honestly, I’m really wanting to build this myself as a marketplace integration for Auth0. If you’re interested, would you mind giving my landing page a look as well and dropping your email? I’m trying to get my own sense on who all wants this before building. Thanks! https://www.keysync.io
