It depends if you are talking about Okta's "Workforce Identity cloud" which is their flagship product under the Okta name and serves businesses needing an IDP to manage their employees. Or if you are looking for "Customer Identity cloud" aka Auth0 alternatives which is primarily for authenticating a businesses end-users/customers.

Microsoft Entra ID formally known as Azure Active Directory is popular option. But the list goes on Ping Identity, One Login, Google Workspaces, and more are all options out there.
