In theory yes but please note that it is 100 request per sec so essentially 6000 users within a min and 360,000 users within the hr concurrently It is unlikely you will run into authentication api rate limits from your organic user login traffic.
Generally it is not possible to raise rate limits. API rate limits are there to protect you and other customers from DoS attacks which can tank server with unlimited api requests. I will encourage you to reach out to Auth0 Sales team though to discuss your specific use case. You can do so by clicking Discuss your needs button from the auth0 Management dashboard.
