I want to get the access token using Microsoft azure username & password.
Is there any API or flow available by using username & password I will get access token.
As per your comment, please follow the detail steps:
https://login.microsoftonline.com/YourTenant.onmicrosoft.com/oauth2/v2.0/token
client_id:b603c7be_Client_id_e61f925
scope:https://graph.microsoft.com/.default
client_secret:NpmwO/KDJ_client_secret:NpmwO_W0kWf1SbnL
username:tenentUser.onmicrosoft.com
password:YourUserPassword
grant_type:password
See the screen shot:
I am getting token as expected
Step: 1
Step: 2
Step: 3
Note:
Requested token user must be a tenant user for example YourUser#Yourtenant.onmicrosoft.com
User password must be correct that you are suing to token request.
Make sure your user belong to azure portal on your tenant
Your Client Id belongs to that tenant
Application secret is valid or not expired.
For more information you could refer Official document
Feel free to share still you are having problem.
I am required in Java or any rest API using that I can develop in java
Microsoft identity platform supports the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant, which allows an application to sign in the user by directly handling their password.
Send below request in java and after successfully it will return access token.
POST {tenant}/oauth2/v2.0/token
Host: login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded
client_id=6731de76-14a6-49ae-97bc-6eba6914391e
&scope=user.read%20openid%20profile%20offline_access
&username=MyUsername#myTenant.com
&password=SuperS3cret
&grant_type=password
Microsoft recommends you do not use the ROPC flow. In most scenarios, more secure alternatives are available and recommended. This flow requires a very high degree of trust in the application, and carries risks which are not present in other flows. You should only use this flow when other more secure flows can't be used.

I have a requirement to provide API to our consumers. The intention is to secure the API using AzureAD B2C - Client Credential Grant flow.
I have created a custom policy on B2C tenant that provides the access token. Things work fine with the clientId and Secret authentication method.
I now want to secure the OAuth2 conversation further by allowing the client to use the signed client_assertion as opposed to static client secret using their protected key. I have uploaded the public portion of the key into the relevant app registration.
Unfortunately, consuming the /token endpoint with the signed client_assertion results in an error.

HTTP/1.1 400 Bad Request
{"error":"invalid_request","error_description":"AADB2C99027: Policy 'B2C_1A_Demo_ClientCredentialsFlow' does not contain a AuthorizationTechnicalProfile with a corresponding ClientAssertionType.\r\nCorrelation ID: 5eb76fa5-c919-4877-a722-0d38408e18c6\r\nTimestamp: 2023-01-19 07:38:25Z\r\n"}
Can someone please tell me if B2C is intended to support client assertions? Metadata JSON on the policy returns only the following two authentication methods:
"token_endpoint_auth_methods_supported": [ "client_secret_post", "client_secret_basic" ]
Is it possible to include private_key_jwt as a supported authentication method using custom policy configuration? Is it possible to configure the AuthorizationTechnicalProfile for the policy with a corresponding ClientAssertionType?
I hope that I have explained the problem well enough.
I have tried various strategies, incluling the use of AAD token endpoint, login.microsoftonline.com with the B2C tenant Id. Using that endpoint, the custom policy on B2C is completely ignored, therefore generating a vanilla token with none of my curated claims.
TLDR: As of June 2022, Azure AD B2C does not support client assertions.
This issue on Github asks for documentation for error number AADB2C99027. In the course of the discussion, a member of the team states
Unfortunately, we decommissioned client_assertion flow because it didn't follow OIDC spec – So we shouldn't be documenting the error.
From that, I take that there are no plans to support client_assertion flow.
I am trying to create an online meeting with a web application using the Microsoft Graph API.
When I try to initiate an authorization request to get permissions from the end-user to create a token with a similar URL to:
https://login.live.com/oauth20_authorize.srf?state=xxx&scope=https%3A%2F%2Fgraph.microsoft.com%2F.default&response_type=code&approval_prompt=auto&client_id=xxx
I get the following error message from the Microsoft API:
The client does not have a secret configured. If you are the client
application developer, configure a secret through the application
management site at https://go.microsoft.com/fwlink/?linkid=2083908.
I have a secret configured for the application in the "Certificates & secrets" part under the "Client secrets":
I have no clue what I am missing here and the Microsoft documentation is not really helpful.
The solution was to change the authorize and token endpoint to https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize and to https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token respectively as it is described here.
In my case - since I want to support multiple tenants - I could not fill out the {tenant} part of the URL with the actual tenant id, but I needed to set organizations since as it is described here only work or school accounts are supported.
So the final URLs changed to the following:
Authorize: https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize
Token: https://login.microsoftonline.com/organizations/oauth2/v2.0/token
I have an secured API student API which I am able to access via OAuth2.0 client credentials flow which creates an access token using IConfidentialClientApplication app and accesses secured app.
Now comes to access the secured API using OAuth 2.0 Resource Owner Password credentials. I have mostly used the code in microsoft github page.
https://github.com/azure-samples/active-directory-dotnetcore-console-up-v2
I am able to sign in using username and password, able to generate access token as well. But this access token is not able to access my secured student API. Though the sample code is able to access the Microsoft graph API, it is not able to access my secured API.
I tried to allow public client flow for my secured student API as well and decrypted both the access tokens to see the difference. There is a lot of difference. What I noticed here is in ROPC flow are using IPublicClientApplication where I am not able to give the ResourceId while acquiring token. So "aud" is different in ROPC token and other fields as well.
Can anyone tell where I may be going wrong or how to fix the above scenario?
I think you may need to perform these 2 steps to get a token valid for your own API:
Expose an API scope in your Azure AD API Configuration
Add an API permission in your Azure AD Password Client Configuration
See step 6 of my Azure AD Blog Post for how this looks. The article also explains some token differences.
I am trying to connect to API through Client AAD details(clientid,client secret) using "client_credentials" grant_type, I am able to fetch the token with API scope but when I use that token to retrieve API results, I am getting 401 unauthorized error.
I am trying to understand what kind of permissions are required on API AAD for Client AAD to accept the token. Please help me to understand this.
Following are the permissions on both AAD :
API AAD:
User.Read - > Delegated - > Sign In and read user profile
Client AAD:
User impersonation - > Delegated - > FOR API AAD
Microsoft Graph - Delegated,Application ->User.Read.All
Thanks,
Deepak.
If you use Client Credential flow to obtain an access token, you must create an application and grant application permissions to the application (this is because Client Credential flow has no user interaction).
Before that, you need to understand the difference between delegated permissions and application permissions:
Application permissions allow an application in Azure Active Directory to act as it's own entity, rather than on behalf of a specific user.
Delegated permissions allow an application in Azure Active Directory to perform actions on behalf of a particular user.
Then you need to define the application permissions by editing the list of api applications.here is an example.
Refer to this document and use Client Credential flow to get access tokenhere:
1.First you need to get the administrator's consent:
GET https://login.microsoftonline.com/{tenant}/adminconsent?
client_id=6731de76-14a6-49ae-97bc-6eba6914391e
&state=12345
&redirect_uri=http://localhost/myapp/permissions
2.Then you can get the access token by sharing the secret:
POST /{tenant}/oauth2/v2.0/token HTTP/1.1 //Line breaks for clarity
Host: login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded
client_id=535fb089-9ff3-47b6-9bfb-4f1264799865
&scope=https%3A%2F%2Fgraph.microsoft.com%2F.default
&client_secret=qWgdYAmab0YSkuL1qKv5bPX
&grant_type=client_credentials
Parse the token and you will see your custom roles:
Okay, now you can use the token to access your resources.
Business Requirement:
We want to replace our Skype meeting URL with Teams meeting on our production system(within a ABAP daemon service without user integration). So I am trying to integrate with Teams using Microsoft Graph API to be able to generate one online meetings. Then this online meeting URL will send to our customer with a mail.
Target Graph API: For MS Graph API V1.0 verion, I think this in only one option Create onlineMeeting.(Graph API with /beta version is not a good option for production usage).
According the MS Graph documentation V1.0 Create onlineMeeting, this API only support permissions with Delegate type. I think we could only use use username/password authentication flow. Correct me if I'm wrong.
Issues: I'm trying to get token with user and password as describe with ROPC Microsoft identity platform and OAuth 2.0 Resource Owner Password Credentials, use following API to test it with my corporate mail.
POST /{{TennatId}}/oauth2/v2.0/token HTTP/1.1
Host: login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded
SdkVersion: postman-graph/v1.0
Content-Type: application/x-www-form-urlencoded
grant_type=password&client_id={{ClientId}}&client_secret={{ClientSecret}}&scope=https://graph.microsoft.com/onlineMeetings.ReadWrite&userName=MyCorporateMail#org.com&password=MyPassword
But, it will always get invalid_grant response: AADSTS50126: Error validating credentials due to invalid username or password.
I don't know why it cannot get token response with my corporate(work) mail/account **#sap.com, I'm sure my password and other parameters are correct.
And if I use a new-test-user sapse#wardsap.onmicrosoft.com which is created by Azure Active Directory, I'll get token successfully. This user doesn't need Two-Step authentication when login to Azure. But this user does have Teams/OnlineMeeting license, so it couldn't generate onlineMeeting.
My Question:
Will it possible caused by MFA configuration from my org? Because I noticed that every time I login to https://aad.portal.azure.com/, it has second authentication step, verify with my Phone message.
If yes, will it be possible to disable MFA to some test/dev account forever? Where should we config it? Within MS Azure or some where else? Who should I get support from?
For this Create onlineMeeting API, do we have other authentication flow for this Delegate permission type for a back-end daemon service?
Thanks and Best Regards,
Ward
MFA will definitely prevent you from using this authentication flow.
The Resource Owner Password Credentials flow and its use are discouraged.
There are many flows which are more secure, and usually you can use ones like authorization code flow to achieve what you want.
MFA is configured by your organization, you'll need to contact your IT about that.
But I would not recommend disabling MFA for this.
A back-end daemon application needs to either use application permissions or a refresh token.
If the API in question does not support application permissions, you can acquire a refresh token for a user through the authorization code flow, store it securely, and use it whenever you need a new token.
If you do this, be sure to overwrite the old refresh token with the new one that you get when you ask for an access token.
