Hey there @helen1 and welcome to Auth0’s Community!
I apologize for the delay in response. To use the lock capabilities in such a fashion you would need to leverage an app you constructed with it’s own codebase and add in the Lock library. I hope this aids you on your quest but if you find you have more questions down the road please let us know!
On a side note we just released an Auth0 Wordpress Plugin Video Walkthrough that could be handy to look at! Check it out below:
