I think Okta will try to build "Okta for Customer ID"
When people think of Okta, they think of it as a tool to help employees securely access third-party SaaS vendors.
That same problem exists for Customer Identity, but it looks a little different. Instead of setting up SSO for SaaS, developers are writing code to pass their customer data into tools like Stripe, Intercom, Salesforce, Segment, Mailchimp, etc, etc.
This is redundant work that a centralized Customer identity provider has the potential to alleviate.
I don't really think Auth0 is well-positioned to pull this off, and that's part of why we started Clerk. But considering Okta has that playbook in it's DNA, I wouldn't be surprised if that's what they're attempting.
