Please ping me if this doesn't work for you.

Thanks,

Unlock account is now a first-class member of the Auth API, and the flow here is very different than the flow there, so I don't think we want this link. In the User API, the unlock functionality is an "admin unlock", where all you do is POST to the users/{id}/unlock endpoint and it unlocks the account. The Auth API handles it from a user-initiated flow, and involves sending a recovery token to the user via email (the Auth API just returns the recovery token to the client app, which can generate its own email to the user, branded as its own company instead of Okta). The user has to then come back to the app with their recovery token and the app has then come back to the Auth API and redeem it for the user's security question. The user then has to answer the security question correctly, and only then is their account unlocked.
