Nancy Selfhosting and google authentication - oauth-2.0

I can't find any proper sample about
google (or facebook) authentication in case of using Nancyfx as a Self-Hosting program.
Advice needed.

Sorry there is no official code/sdk for Nancyfx.
But if you want to support basic "Sign in with Google" on any site the easiest is to add some code on the page (this can get you an id_token)
https://developers.google.com/identity/sign-in/web/
And send this id_token to your server and validate it on the server side. The code to validate is fairly simple. You can pick up the sample python or java code from here.
https://developers.google.com/identity/sign-in/web/backend-auth
This is probably the easiest way to get Google sign-in on a web based application.

Integrating mautic server with another java application

I'm new to mautic. We have an java application that manages authentication of its users. It also support openid connect/ jwt/oauth flows. We are planning to use mautic as a separate server . How do I integrate my application with mautic? Seems like the mautic only support SAML for SSO. Does that mean our application now need to act as SAML IDP? Or is there a way to get mautic to support JWT/oauth/openid connect
Can you clarify why you need to authenticate users, will these all be people who will be working in the back-end of Mautic? Otherwise you won't need to use authentication for regular folk accessing resources or landing pages you create, they don't need to log in.
The developer documentation would be a good place to start for all things technical/development, which you can find here: https://developer.mautic.org/ - this includes information about authorisation and specifically OAuth which might be helpful: https://developer.mautic.org/#authorization.
You'll find some documentation on using the SAML function here if you're going that route: https://www.mautic.org/docs/en/authentication/saml.html
Happy to help if you get stuck!

How to understand when oauth is being used

I am trying to understand in what scenarios I should be using oauth. From reading the spec, I understand that you are essentially delegating identification to a 3rd party.
So if we take the example stackoverflow's login page you get
Oauth2 is being used for google and facebook, how do I determine what stackoverflow is using (when entering username and password directly)? Would that also be oauth 2? If it is using oauth, how would I go about understanding which flow they use?
Your question is a little unclear but what I think you're asking is if SO or some other site uses oAuth for all their authentication schemes. They could. If they using oAuth with user password authentication when you authenticate, the response you get back should have an Authorization Token and a Refresh Token in it that you would then use to authenticate on each successive request. Hope this helps. oAuth isn't a technology it's a protocol on how to do authentication in a better way.
See what is the request URL when you click to log in with gmail...

Does that auth2 means oauth 2 ? I think so
UPD: As I understand OAuth mechanism is supported by 3-rd part. SO could use their own oauth for direct enter, or standard auttentication. It is up to SO.
To keep it short and easy:
If you want to add authentication to your application and you want to leave some security heavilifting to big companies like Facebook, Google and Stackoverflow it is generally a good idea if you do not know precisely how to handle such a delicate task and/or you are not using a specific Auth tool / framework.
On the other hand, from the user perspective, the application will be far more user friendly (just one click authorization instead of a painful registration).
If you want a much more detailed technical explanation I suggest you to read this other Stackoverflow post:

The authorization method of One Drive

I would like to know if One Drive supports those four ways of Authorization. Please refer to this link. https://www.rfc-editor.org/rfc/rfc6749#page-23
We are integrating our DVR and NVR with One Drive now and we need to understand which authorization method One Drive supports. We are trying to use OneDrive with embedded ARM processors, so the user does not have access to a browser as they would for a web-app.
Please kindly advise how we should proceed from here. Thanks for your time and I look forward to hearing from you.
Best Wishes,
Ted Yang
I am going to say yes, OneDrive probably supports those ways of authorization, because on their authentication documentations page they say the following:
The OneDrive API uses the standard OAuth 2.0 authentication scheme to authenticate users and generate access tokens.
That link takes us to the oauth.net site page for OAuth 2.0. On that page, we find the following:
The final version of the spec can be found at https://www.rfc-editor.org/rfc/rfc6749
which is the document you linked. The OneDrive API documentation says it supports OAuth 2.0, and your linking the definition of OAuth 2.0, so I think it's safe to say it's supported. How to use it is another question entirely, and one I am unable to answer.
I will note, however, that on the OAuth page, they have this to say about it's uses (emphasis mine):
OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and living room devices.
I would presume that living room devices could include DVRs, and although your DVRs are for security purposes, the development of cloud storage APIs for either would undoubtedly be similar. So I would say this is probably quite possible.
How to do it:
First things first, you'll need to register your app. This gets you a client id and a client secret which you'll need. Registration directions
There are two methods: token flow and code flow. Token flow is two steps, and code flow is three steps. However token flow uses tokens that expire, so it would require the user to reenter thigns periodically. You therefor want to use code flow. Here's some directions for that.
Basically the steps of the code flow are:
Get an authorization code
User authorization code to get an access token
User access token to make API calls
You WILL need to make HTTP requests. I'm sure you should be able to do this with ARM embedded C. However, step 1 is what gives you to the Microsoft account login page. I am note sure how to circumvent this, exactly. I'm not sure you're supposed to be ABLE to circumvent this, since Microsoft doesn't want you handling their customers' passwords.
They have an example in Javascript that might give useful details on oauth in the oauth.js file. Javascript sample project

Claim based security with MVC custom login page

I am developing MVC application and want to use WIF & Claim based security.
However I am very disappointed with the way login is perfomed. I mean redirection to STS login page and then redirecting back to my page. That is not user-friendly at all.
I want to implement login page in my application (it fact it will be popup dialog). Than using Web API I want to be able to perform STS request and get security token and initialize WIF infrastructure (Principle etc).
Is it a good way to go with?
Did anybody do something similar?
Does anybody have some samples of what I am trying to do?
I just worry that I don't have control over the STS login page layout & style.
Also I will have mobile application and must perform login using Web API service.
What can you advice?
Thanks
Well - you can do that of course. This does not need to be WIF specific. Call a service, pass credentials - and when OK set the login cookie.
But if you want SSO you have to make a user agent roundtrip to the STS - otherwise you cannot establish a logon session.
Consider using MembershipReboot membership provider which uses claims-based security and is not based on microsoft's traditional membership provider.
It does not have a documentation, but in the zip file you can find 2 sample projects that uses MemebershipReboot provider, which explains all you need to know about it.
In fact after reading this blog post today, I decided to use this approach in my current project. I'm still struggling with it now and I'm so excited !
In addition to Ashkan's recommendation Brock Allen provides solid documentation about how to implement MembershipReboot in association with IdentityServer. You can find that their is a way to configure a custom implementation Here. Also their are a few tutorials on vimeo from Dominick Baier (leastprivilege) that will provide a full walk through on getting started! I hope this helps!

How to programmatically obtain OAuth2 client credentials for Google API

I'm trying to create a redistributable web application that will integrate with Google Analytics through the Google Reporting API. Customer will install the application on their server.
I'm following this tutorial (I'm using PHP, but I believe this is not of importance for my question)
https://developers.google.com/analytics/resources/tutorials/hello-analytics-api
This works fine. No issues there.
However I can't figure out one missing element:
The tutorial starts with sending me to the Google APIs console where I have to create and configure a new API project and create and configure a client ID.
That's a lot of work that requires fairly technical knowledge (redirect url, selecting correct API, error-prone copy-and-pasting, etc.)
So my questions:
Is there an API so I can programmatically set this up for my user?
If that's not possible, is there a more user-friendly way to obtain Analytics reporting that is future-proof? (I noticed they are currently deprecating a few older APIs)
Unfortunately that's AFAIK not possible.
You could go one of the following ways:
Move client_id and client_secret to some configuration file and help your customer with deployment.
Show a one-time setup wizard for your app and guide your customer step-by-step. There you can at least provide him with the right callback URLs.
Regard your application as "installed application" and instrument curl or something similar for sending the requests.
