Password Reset with Code for WordPress REST API

A simple plugin that adds a password reset facility to the WordPress REST API using a code. The process is a two step process:

1. User requests a password reset. A code is emailed to their registered email address
2. The user enters the code when setting a new password, which is only set if the code is valid and has not expired

It is also possible to check the validity of a code without resetting the password which enables the possibility of setting the password by other means, or having a two stage process for checking the code and resetting the password if desired.

Default settings are to use an 8 digit code consisting of numbers, upper and lower case letters and special characters, which has a life span of 15 minutes, afterwhich a new code would need to be requested. By default a user can attempt to use or validate a code up to 3 times before automatically invalidating it.

Endpoints

The plugin adds two new endpoints to the REST API:

• Endpoint: /wp-json/bdpwr/v1/reset-password
  — HTTP Verb: POST
  — Parameters (all required):
  — email

• /wp-json/bdpwr/v1/set-password
  — HTTP Verb: POST
  — Parameters (all required):
  — email
  — password
  — code

• /wp-json/bdpwr/v1/validate-code
  — HTTP Verb: POST
  — Parameters (all required):
  — email
  — code

Example Requests (jQuery)
