/**
|
||
|
|
* useSupport returns the Support secret that the server requires for Support
|
||
|
|
* actions... if the user has it set. For most users, this returns nothing!
|
||
|
|
*
|
||
|
|
* Specifically, we return an object of:
|
||
|
|
* - isSupportUser: true iff the `supportSecret` is set
|
||
|
|
* - supportSecret: the secret saved to this device, or null if not set
|
||
|
|
*
|
||
|
|
* To become a Support user, you visit /?supportSecret=..., which saves the
|
||
|
|
* secret to your device.
|
||
|
|
*
|
||
|
|
* Note that this hook doesn't check that the secret is *correct*, so it's
|
||
|
|
* possible that it will return an invalid secret. That's okay, because
|
||
|
|
* the server checks the provided secret for each Support request.
