Keystone Forgotten Password

What is This?

Note

This plugin assumes you have a user model with a password property with a keystone Password field type.

	const forgotPassword = require('keystone-forgotten-password'); 
	
	// Exposes a single route to change a password for a logged in User.
	const { updatePassword } = require('keystone-forgotten-password');

Prerequisites

• Node V6+

Forgotten Password

// routes/index.js
const forgottenPasswordPlugin = require('keystone-forgotten-password');

const forgottenPassword = forgottenPasswordPlugin({
	// define what happens on the given email handlers.
	onForgotEmail: (locals) => sendForgotEmail(locals),
	onChangePasswordEmail: (locals) => sendChangePasswordEmail(locals),
});

exports = module.exports = function (app) {
  app.get('/', routes.views.index);
  app.use('/auth/', forgottenPassword); // routes are mounted on /auth/ auth/forgot, auth/change-password will be added
};

// model/User.js
const keystone = require('keystone');
const { enhanceUser } = require('keystone-forgotten-password');

const User = new keystone.List('User');

User.add({
	email: { type: keystone.Field.Types.Email },
	password: { type: keystone.Field.Types.Password },
});

enhanceUser(User);

User.schema.virtual('canAccessKeystone').get(function () {
	return true;
});

User.defaultColumns = 'displayName, email';
User.register();

Update Password for Logged in Users

In the case where you have a 'Profile' page in your application and you want to allow user to change their password setup the following.

// routes/index.js
const { updatePassword } = require('keystone-forgotten-password');


exports = module.exports = function (app) {
  app.get('/', routes.views.index);
  app.use(middelwares.authenticated, updatePassword()); // route is added to /update-password
  // alternatively
  app.use('/profile', middlewares.authenticated, updatePassword());
  
  // forgottenPassword checks by default req.user from your custom middleware, want to check a different property i.e. req.appUser?
  // want to send an email?
  app.use('/profile', middlewares.authenticated, updatePassword({
  	userRequest: 'appUser',
  	onChangePasswordEmail: (locals) => sendChangePasswordEmail(locals),
  }));

};
