Challenge #1 of 1

Q:
I'm working on adding the `switch_user` feature to my site. To switch, I know that I can add `?_switch_user=` to the end of any URL. But... instead of using the user's email address, I want to be able to use the user's `id` in the URL. Is that possible?

Yes: you can use either the email or id out-of-the-box.

No: only the value returned from getUserIdentifier() can be used.

Yes: there is an option under switch_user to choose which property to query.

Yes: by configuring your user provider.
