How does Dynamic Client Registration effect Application quotas?
Once enabled I cannot control who creates applications so could a malicious user use my quota up?
Hi @adam22,
Welcome to the Auth0 Community!
Those clients created with Dynamic Client Registration will contribute to your tenant/subscription Entity Limits.
How can we limit abuse if we turn this on? With self-service the limit is 100? Is there a recommend way for building a typical developer portal for third-party integrators to use our APIs offered in other solutions?
If you are planning on having users (developers), you could create a dashboard for registered users and register third party apps via the management API. You can do this without DCR.
Thanks yeah makes sense. The 100 limit is still a fairly low default limit in my opinion for paid especially with more of a public developer portal. Compared to other options more geared for API access. I know we can pay for more 
Thanks for the feedback. Let us know if you have any other questions.
