How to link user between Wordpress vs. Parse.com db's - wordpress

I am using a web site installed with Wordpress and a Mobile app that uses Parse.com to store its data.
Now I want the User Registration on either solution to automatically register a user on the other.
Example: When a new user register on the Wordpress based web site a PHP script should automatically create a User Object in Parse.com datastore - and here is the problem - WITH SAME PASSWORD!
I can easily create a user in Parse.com data store from the action hook register_user from Wordpress, but how do i transfer that same password to the new Parse.com user account, so that when the user next time log in through the Mobile app, they just use the same password as they used when registering their account in Wordpress?
The other way around, when registering as a new user in the Mobile App saving to Parse.com User Object, how can the same password be transferred to a Wordpress user account!

I realised that exchanging passwords from one database to another is not the solution, neither does OAuth solve my problem. only solution is to stick with only one database being called from both systems - at least for the account information.

Firebase subaccounts

I'm currently building a POS/Store admin app, when a user gets into my app, the Owner of the store will then be asked to login only once for setup purpose (e.g. a new machine), the app will then display a list of staffsName that has already been added by this owner, and then everytime a staff wants to start a new transaction, he/she will only need to click on his/her name, then enter his/her 4-digit pincode to 'login' and process the transaction.
How do i go about achieving this?
I was thinking of using firebase auth for the 'login' of the staff, but then when i log in using the staff credential, I will lose access to the uid of the owner, which is needed to access the owner's store data such as his/her products.
i'm also thinking of using firestore to store the 4digit pincode, but then i'm also concerned about security
There are multiple ways you can approach this, one where you utilize the email login by simply appending a fake domain to the username to create a valid email domain. This user account could be the designated 'user' in question, or utilize credentials inside custom claims or hidden in a database that allows the client or server (depending on your preference) to then log in as the user.
Moreover if you want the manager to login once you can add Authentication State Persistence to specify whether a signed in user should be indefinitely persisted until explicit sing out, page reload etc.
Another approach requires the user also to have a valid auth that is not an email password and you link your pin auth to that main account with Firebase Auth Linking per the documentation: https://firebase.google.com/docs/auth/web/account-linking.
This does however require that the user be registered from an auth provider such as Google, Twitter, Apple, etc. then the user will have to activate this link by logging in for authentication purposes. This can in theory be automatically generated and processed without the user knowing.
It is a long way around it since this is essentially a custom solution but it does create the flow you are looking for without having to use a custom auth provider.

WP REST API - User registration without authentication

I am just starting out with using the WP REST API.
For authentication, I use JSON Web Tokens.
The only question I have is how I can give users the possibility to register by themselves, since registering a user also requires an authentication key.
Since the user has not yet logged in, this key cannot yet be retrieved.
I came up with the following two options, but cannot figure out how to do either of them.
The application itself has an authorization key with which the request can be made.
Disabling authentication requirement for user creation.
If I'm looking at this in the wrong way, any answers are welcome!
Thanks!
If your application is a web page then the easiest is to do this separately from the WordPress REST API. WordPress has a web page http://aaa.bbb.ccc/wp-login.php?action=register that allows you to register new users. To enable this web page check the Dashboard -> Settings -> General -> Membership -> 'Anyone can register' option.
If your application is a mobile app then your mobile can just sent the same HTTP request that http://aaa.bbb.ccc/wp-login.php?action=register sends. I.E. a POST request with query parameter action=register with POST parameters user_email, user_login, wp-submit=Register.
If you really insists on doing this using the REST API I think the following will work. (Disclaimer: I have not actually implemented this.)
You will need to override the WordPress REST authentication. First create a new role with the capability 'create_users'. Second create a user with this role. Create a nonce that specifies that a new user is to be registered. When your app returns this nonce and the user credentials to the http://aaa.bbb.ccc/wp-json/wp/v2/users endpoint you should override the WordPress authentication to set the current user to the user you created with the role 'create_users'.

How do I migrate existing Wordpress/WooCommerce users to LDAP?

I have a Wordpress/WooCommerce installation using Wordpress itself for authentication. I want to switch to LDAP-based authentication (e.g. OpenLDAP). How can I migrate existing users with minimal intervention on their part?
Ideally they would simply continue using their pre-existing credentials for Wordpress and for any other resources using the same LDAP database.
In addition, new users created via WooCommerce purchases should be created as LDAP users.
(Existing plugins like Simple LDAP Login seem to handle creating Wordpress users for pre-existing LDAP credentials just fine. I'm looking for support in the other direction.)
I think you'll have to develop this task yourself. You could check tools like : https://lsc-project.org/start which will allow you to configure mapping and synchronising SQL database to LDAP directory and schedule the task regularly (or trigger it on new row in the DB)
Only point where you could have some problem would be the "keep their credentials". I don't know wordpress, but if the hashing and/or crypting mechanism of the passwords are not natively supported by OpenLDAP, you will have to hash the clear password of the user to store it with a mechanism compatible.
One way would be to tell every user that the password will be reset and that they will have to retype it (some custom landing page where you authenticate the user with his credentials on the wordpress DB and if successful write the password on the LDAP)
Another way would be to deploy some self service password with all account reset and a need to re-set them with a link send to their email (from the LDAP). There are tools like that, for example : https://ltb-project.org/documentation/self-service-password
Follow Esteban's advice I developed a solution as follows:
Wordpress interface
Install Simple LDAP Login
Install JWT Authentication for WP REST API
Users authenticate against LDAP, fall back on Wordpress
"Change password" sends them to new interface
New interface
User logs in via new interface
Users authenticate against LDAP, fall back on:
Authenticate against Wordpress via JWT. On success:
Create LDAP user (we have the password)
Delete Wordpress password hash (no longer needed, forces LDAP-based authentication in future)
Workflow
Existing users can sign in via Wordpress or the new interface. Once they use the new interface (to sign in or change their password), they are migrated to LDAP-based authentication.
New users are registered in LDAP. They can sign in via Wordpress or the new interface, both backed by LDAP.

Single Sign On (SSO) between Wordpress and CakePHP

I have an existing Wordpress site. The plan is to rebuild the site using the cakePHP framework. Due to time restrictions, I want to replace individual sections of the Wordpress site one at a time. This will mean that both apps will be running side by side for a certain period of time. I need to control access to the cakePHP app using the authorization provided by Wordpress. I'm not sure the best way to go about doing this. I've seen similar questions asked a lot, but I have not yet found a clear solution.
I'm thinking about two approaches:
Plan A:
Configure Cake to look for Wordpress's authorization cookies.
configure Cake to look at Wordpress's database.
Borrow some of Wordpress's authorization logic to teach Cake's Auth component how to authenticate WP users.
Plan B:
set up an authorization API on my Wordpress site.
set up separate auth component in cake.
ping the WP endpoint when a user hits a protected page in the cake app and then manually log in the user. (This would create a second set of auth cookies)
Do either of these sound like the right approach? Is there a better way to do this?
Helpful references: Article about Cake session handling, Cake Auth component documentation, Cake Auth tutorial, brief overview of WP authorization, a more in depth look at wordpress authorization
UPDATE
We've started working on this, and it seems like it will work, but there is a very tricky aspect involving password hashing that warrants its own question. If you're following this thread, you may want to have a look.
I once had a similar situation: Cross framework authentication zend + codeigniter which was few months ago...
Anyways, this is what I will prefer:
set up an authorization API on my Wordpress site.
set up separate auth component in cake.
ping the WP endpoint when a user hits a protected page in the cake app and then manually log in the user. (This would create a second set of auth cookies)
Here, I would suggest a slight change which is do-able.
Make sure, you have a token system of SSO. As in, when person is logged in on Wordpress, set another cookie which will have a token: Token will be username + password (hashed) + secret key, which will be same between Wordpress and CakePHP. On either site, look up for cookie and manually log the user in or just perform a database look up. Hashing is important for that cookie!
However, if the site is using different domains, you might need to re-strategize:
I had different domains once. At the login or unauthorized page, I would ping the other website and bring up their login box. On the other website if the user is logged in, they get post login page and if request URI has sent a token, we perform normal operation and return the authorized token to this (current) domain.
In simple words:
Site A = WordPress & Site B = CakePHP
Site B hits a page where authorization is required then, ping Site A for a login (as it happens when u do Login-with-Facebook sort), which will request via a Token (private key) and REQUEST_URI which will be part of SSO verification table on Site A, if person is already logged in then, Site A will return (via POST) a token, which further will be decrypted via (private key) of Site B and log the user in. Private key of B and A will be same.
Hope this was understandable.
Questions? :)
Answer to your questions in comment:
Ideally, why we use SSO? We use it because of many constraints. For example: You have a database of say... a million row with more than thousand tables, you need to add a module over ur huge app already... so, instead, you will use another database... SSO will return user information, which can further be replicated. For example, when you click on 'Login with Facebook', it returns requested information, like email address, or user's name or even profile picture. Which can further be added to our database... Keeping different databases is strongly recommended :)
To your 2nd and 3rd question: Should both sites reference the same users table in the database? different databases is recommended unless, you are using the same data. Or say changing the software platform.
Should I copy the site-specific user rows into separate user tables for each app? Yes, that should happen automatically. Once you are registered on a main site, nothing happens, things should happen once you are logged in already and then go to site B... Once logged in, user info can always be requested :) That way, new site will have active users ! 2 birds?
Don't complicate (bother) yourself with how what works but, concentrate on how, what is achievable in short period. SSO - Logged in - Restricted page - Look out for log ins - Either login - If already logged in - fetch user info - If user info exists - login via secondary site OR set the new user info . Done!
We developers love flow charts! Don't we? I just created one:
Further answers:
Does the "Fetch User Info" stage mean that we take the user info from the site which is logged in, and create a new user (row) automatically in the other site?
Ideally, you will ask permission from the user before they 'allow' their info to be used but, it varies how your privacy policies are.
In other words, one site handles all the registration/user-creation and the other site just waits for that user to show up and trigger automatic creation. OR at the moment a user registers on the one site, BOTH databases get a user row inserted?
one site handles all the registration/user-creation and the other site just waits for that user to show up and trigger automatic creation. You can have both. Sign up on your website and also a trigger based automatic creation. Depends on your strategy. OR at the moment a user registers on the one site, BOTH databases get a user row inserted? That would be a horrible practice! It will kill the motive of SSO. Motive of SSO is to create an auth family which can be used by users so that they do not have to register every now and then for different websites. update only one database at a time and other when required :)
Questions? :)
I have done this once. I don't have the snippets and/or any references to anything. But thought it might be helpful.
Configure WP and CakePHP both to use same session, you can do this by session id and session name,
When User registers for your website, register them using both WP and CakePHP,
Choose one framework that will handle login view from the front end. I had chosen CakePHP as I was more proficient with it, once the login is successful locate the same user in other framework's DB and authenticate the user using their authentication system.
Hope this helps !!!
Suggestions:
If you are building a closed system, meaning you have to be signed in to access anything useful in the site, then you can use CAS . I know it's used by mainly universities, but for closed systems it works.
( If you need to handle anonymous users the suggestions below might help)
Keep it simple and, similar to Part A of your plan, have a cookie ( visible by both cake and wordpress ) that simply states if a user is logged in. The cookie should be created/checked by both cake and WP. Cake does not need to look at WP's DB. The cookie can have information on how the users in each system are mapped.
Have a central login screen, this is similar to what CAS does. But please build your own. CAS does not handle anonymous users. I am currently creating a central login screen for work. It's simple. The central login screen will handle all authentication and create the cookie visible to both WP and cake. This would mean that the login link for WP and cake will redirect a user to a common page. The link will need to provide a callback URL so that after the user authenticates successfully, he is redirected back to the original service. You will need to decide on a central DB for user authentication.
The cookie approach has following bonus:
It's a lightweight solution and can be wrapped with an on/off switch. In WP, simply wrap the cookie logic with a wp_options value.
You can use WP's and cake's authentication system. no need to work with API's and/or sessions. No need to couple applications by looking at each other's DB.
You can keep roles and permissions native, meaning WP will work with it's own roles and permissions system and your cake application will work with it's system.
Adding a new "service" to your platform is as simple as "create/check for a cookie" then use the system out-of-the-box auth system to log the user in.
Single Sign On is as simple as creating a cookie. Single Sign Off would be deleting the cookie.
I can definitely go into more detail on each suggestion if you're interested.

How to - Facebook Connect with existing user table

I have a registration-login system on my own website yet I want to add Facebook Connect too. I have some required parts of my user table as:
Username
Password
Email
The first thing that came to my mind is, setting userId as username, userId#facebook.com as email and setting the password to null and check if a record exists with these details in my user table. If not insert a new user with these details, if exists return that user details.
Is this a good design? How should I connect facebook connect to my website?
Thank you
I would suggest you to take this into a more deep ASP.NET, and start an MVC project
then use the Microsoft Facebook API SDK to play around with the API, it's very easy and because they are using the new dynamic type, now that Facebook changed the Open Graph, it will continue to work great as well.
in your login page, add a facebook login button and ask for permissions, for example:
<fb:login-button perms="email" size="medium">
redirect-uri="http://yourdomain.com/FBLogin/"
Subscribe using Facebook</fb:login-button>
in your FBLogin controller, login the user using the FB credentials, if the user uses your normal form, use the normal login
If you create a custom MemberShip Provider, you can easily use that for both accesses... I write a simple start to a custom Membership provider here
