Allow user to change their password and enable / disable MFA from within a single page react app?

I found this post Allow the user to change their password from a profile screen and it sounds like it I have to implement this myself using my own backend…?

I currently use Cognito, which allows a client to do this, see ChangePassword - Amazon Cognito User Pools

I don’t understand why such a common feature would not be supported by auth0… Implementing this myself is certainly possible, but it just adds one more surface for attack, or someone to accidentally log passwords, etc… isn’t this the whole reason for using a service like auth0?
