I'm developing angular6 web app with mobile view.
For authentication I'm using keycloak server. It provides me with Oauth2 with access and refresh tokens.
For obtaining tokens user have to login with login/password.
It's not very comfortable for user to enter password in mobile each time tokens are expired.
It would be cool if it possible to resume working in application by entering pin code. I think pin code can be set up by user after first login or generated by server and sent to user by email.
How is it possible to configure pin code authentication for web app?
Is it possible to configure pin-code authentication using keycloak?
Or is it possible with another auth server?
Can it be done without storing password somewhere on FE or BE?
You'll need to develop a custom Authentication SPI (service provider interface).
Keycloak has example code in GitHub that demonstrates how to support a secret question for example, which won't be miles away from what you'll need for your PIN code secret.

I am wondering if there is anyway to check if the entered username and password is correct despite of enforcing multi factor authentication in Azure Active Directory?
I have set up an app with application permission(with admin consent) as well as delegated permission and is able to test both approach using ConfidentialClient and PublicClient using MSAL library.
I am not able to run my web form app in IIS with the PublicClient approach which is interactive and displays you a popup for the Microsoft login. So, the only approach I see here is to use app-only authentication.(https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-authenticate-an-ews-application-by-using-oauth )
I can use the confidential client(app only) since I have all the required admin consents granted to get the OAuth token and then impersonate the user to access to EWS managed api.
But the requirement is the user should enter their outlook password in the webform app before loading their emails(from EWS Managed API which needs OAuth token).
At this point I am not sure what to do next. Please help. Also let me know if you need more information.
For more reference why I am no able to use delegated authentication: Why app is throwing error in test environment but working fine in local machine using ASP.NET Web Forms and MSAL?
Per my understanding, you want to check the username and password by Azure AD first and using the confidential client to call APIs on behalf of the user.
This way is something hacking, but I think it works for this scenario. Just try the request below:
POST https://login.microsoftonline.com/<tenant id>/oauth2/v2.0/token
Request Body:
client_id=<confidential client app id>
&Client_secret=<confidential client app sec>
&grant_type=password
&scope=https://graph.microsoft.com/user.read
&username=<username>
&password=<password>
If the user typed the wrong user name and password, the response would be:
If username and password are all right, the response report the MFA related info:
I'm creating a react native app and adding instagram authentication to it. I want users to be able to "add" their instagram accounts to their main user account, so I have a "connect your instagram" button.
I have this working on my web app fine.. The flow is as follows:
User clicks 'connect instagram' button and a new window opens and is directed to https://instagram.com/oauth/authorize/?client_id=xxxx blah blah
User authenticates and instagram redirects to my REDIRECT_URI with a CODE parameter
My API server takes the CODE parameter and sends a post request to instagram with all the credentials.
Instagram verifies this information and gives me the users ACCESS_TOKEN
Can someone tell me how this is supposed to work in an app?
What's my REDIRECT_URI supposed to be? The server api?
Is it the same flow as my web app? If so, how do I get the users back to my app after the window is closed. How does my app know that the user now has an access token?
With a native application the flow is similar to what you described for the web application.
The Auth0 Mobile + API architecture scenario describes what should happen when you need to authenticate a user for a mobile application and then later access an API on behalf of that user.
Summary
you will continue to use the authorization code grant;
if the authorization server in question supports it you should use the PKCE (Proof Key for Code Exchange by OAuth Public Clients) for added security;
you will need to select how you will receive the code in the native application; you can use a custom scheme com.myinstaapp:, a local web server with the http: scheme or a few other options; (see this answer on OAuth redirect URI for native application for other alternatives)
you exchange the code obtained by the native application with an access token in a similar way to what you would do for a web application; (except for the use of client secrets which are in general not useful for native applications as they would be easily leaked)
Additional Information
The flow described in the Auth0 scenario assumes that authentication will happen through an OpenID Connect compliant flow and in addition you'll get the access token as specified by OAuth2. I'm not overly familiar with Instagram so if they only support OAuth2 that part is of course not applicable.
I'm working on a personal project composed of an API and 4 clients (web, android, iOS, windows phone).
I'm using django-rest-framework and oauth2 toolkit on the API side and I wonder which grant_type would be more suitable in my situation.
I read somewhere that the implicit grant_type is appropriate for working with mobile clients.
I'm currently using the resource owner password credentials system.
My current workflow is:
The user creates an account on the API registration page (http://mysite/api/register) then gets redirected on the web client.
The user have to authenticate himself on the API from the web client (the secret and client ID are store in the web client). If the authentication is successful the access_token and refresh_token are both stored in the user session.
Each time the user want to access a page I verify if he is authenticated by requesting the API using his access_token. If the request fails, I retry with the refresh_token. If it's fails again I redirect the user on the auth page.
The user can use the API on a mobile client with the same account without extra manipulations (the secret and client ID are store in a secure location ex. share preferences or keychain)
I like this workflow, it's simple and convenient for the user: he registers once and can use all the clients and I get a perfect separation between the logic (API) and the UI (client). But I'm worried about the security of this system. I don't want to expose my users to threats. Do you guys have any thoughts, recommendations, suggestions?
You help in this matters would be very appreciated.
Thanks in advance!
I use Google Webtoolkit together with Phonegap to build a mobile app. My app is communicating over a REST APi with my Backend Server.
What I want to do is a user authentication, i.e., my app user should be able to signup and login. If a user closes the app and reopens it, he should be authenticated again if he has not logged out before.
Usually, with Spring Security you do the authentication on the server by calling the required methods. The client (browser) then contains some cookie information for a persistent login.
1. How can achieve this kind of authentication for my app?
2. Should I do the authentication as for a normal web site with the only difference that the authentication methods are called by the REST api methods?
3. Is there another way of doing the authentication for my mobile app?
I think user authentication for the mobile app will be the same as for a normal web-app.
The Spring backend will create a session once a user is authenticated. By default the user is authenticated for the duration of the specific session (until the user closes the browser/app).
Spring Security has a Remember-me functionality that is typically based on a Cookie approach and allows the user to be re-authenticated automatically..
I don't know if phonegap work with Cookies (see here for some pointers). I guess it depends on the plattform (if webview supports cookies).
May be this will help you I wrote an article that show how to adapt Spring Security to secure REST services.
You can check it in here : http://crazygui.wordpress.com/2014/08/29/secure-rest-services-using-spring-security/
I also posted a working example which shows how I did use that with GWT on GitHub.
I am creating an android app that has access to an online Database. The initial app activity screen is a login form where the users credential are validated. If the credentials are valid then the app continues to the next activity. I've looked at OPENID and a few others methods. How would I implement OPENID or a another form of user authentication for my app. I would ultimately like to have a third party take care of user authentication and credential storage.
Have you tried looking at OAuth?
http://oauth.net/
OAuth Signpost is an android implementation of OAuth
http://code.google.com/p/oauth-signpost/
Server side, you need to provide an OAuth ready API, if your server is PHP, take a look at
