We implemented Okta Customer Identity for managing external user authentication across multiple applications. Overall, the platform is stable, scalable, and integrates well with modern architectures (APIs, microservices). We primarily used it for SSO and OAuth.OIDC flows, and MFA enforcement. The setup required some initial learning, especially around policies and flows, but once configured, it has been reliable with minimal downtime. It significantly reduced custom authentication logic on our side and improved security posture

It has been a great experience using the product, given that Auth0 is a trusted Identity product, we have not much complains benefiting from the features that the product is getting us. It is up to standard, and we have not much worry to get the platform into production usage. However, Auth0 is not very flexible as a company to deal with better customer support when it comes to providing better value for the price that we have paid, instead hard contractual terms are being pushed while we attempt to negotiate for an exchange of knowledge for a few certain dormant months of the service (which was also paid for).
