how to suppress the login screen in Azure AAD authentication - azure

I have created an Azure app. After granted by user(once in lifetime
), it fetches the users outlook mailbox data with help of accessToken. The Microsoft account is part of my org which uses SSO. So, if i am pre logged in via SSO in browser, how can I get rid of the un-neccesary login screen, which comes pre-populated with my email id, and I only have to click to choose the user account.
How could i remove that login screen from this flow?

You can specify login_hint=user#domain.com with the username in the authorization URL to tell AAD which account the user could use. If they are already signed-in, it won't prompt the user to select the account.

How to sign out from Azure AD automatically right after receiving a mail id from Microsoft Graph?

In my ASP.NET web app I have added Sign in with Azure button. The project has already got its database to authenticate the user. So from Sign in with Azure button I am getting the email id using Microsoft Graph and then using that email id to create the token for specific user from the database.
The issue is that user can have multiple id registered in Azure AD but only single id is registered in Database. After signing in with id (that is not registered in database) Azure will authenticate the user but its email id won't work because that email id isn't registered in Database. The user will be re-directed to the homepage. But now when we again click on Sign in with Azure button then he's not being asked for different account details but signing in with old credentials again automatically.
You can check this out https://login.microsoftonline.com/common/wsfederation?wa=wsignout1.0
This will sign-out all the users from Azure AD using the URL above.

Azure AD B2C SignIn/Signup Flows with Email/Phone Number

Azure B2C User Flow SignUp/SignIn with Email/Number.
Requirements:
SignUp with Email/Phone:
while signing up when user click for registration its shows already email/phone number exist but we are looking when user have already have email then it automatically move to login flow.
SignIn with Email/Phone:
while user click on the signin if user not exist then it automatically navigate to the signup page so user dont need to manuly go for signup
Forget Password with Email/Phone:
With the Email/Phone number signin/signup flow there is missing the reset password policy to change password and there is only showing the change phone number option.we need to reset the user password
There is missing the Cenel icon on the phone number signup flow.
I did reproduce your scenario and found that there is currently no prebuild option or system in user flow of Azure AD B2C that when user try to sign and if it has not already signup will redirect to signup page and vice versa.
Azure AD B2C offers various sign-up and sign-in options for users of your applications:
I did Configure my Azure AD B2C local accounts to allow sign-up and sign-in with using email address. There are also other ways with username, phone number, or a combination of methods.
For Forget Password with Email/Phone enable the self-server password under the properties of your created user flow.
Please follow this GIF for apply for Forget Password with email and attribute which I have set for my userflow.
I have shown the demo how my user flow is working please check this GIF as well.
I have redirected my webapp to https://vikashgaurav.com/portfolio/ after successful signing.

Azure b2c enrolment

We are using b2c for our website, we are trying to integrate with another vendor, they are willing to change their portal to allow our customer to single sign in from our website. Question, how would this flow work, would picture they have a button for enrolment, which allow customer to sign in with b2c credential then they store the credential mapping, then next time whenever customer already login they would automatically login their portal too?
You would federate your vendor with B2C using either SAML 2.0 or OpenID Connect.
Yes, on the vendor side there would be a "Login with B2C" button.
Once logged in, a cookie is set.
You get SSO as long as the cookie is valid.

Detect social account existence flow using custom policies on Azure AD B2C

I am struggling to get my head around how to implement a custom policy for the following flow:
User lands on the login page and that login page only contains an email input.
User enters email address and clicks continue
if user has already registered
Redirected to their selected login provider (Google, Microsoft Account or Local Account)
if user has not registered before
Check google provider if a user account exists for that email address
if Google account exists
Redirect to Google login
Check Microsoft provider if a user account exists for that email address
if Microsoft account exists
Redirect to Microsoft login
else
Redirect to registration screen
User completes registration screen
User is automatically logged in
The user
I've investigated whether this can in fact be done and I've found a "digital workspace for visual collaboration" (a.k.a Mural.co) that does in fact implement a similar flow, so this has to be possible. See the pictures below.
I'm, however, unable to find information on
how to query the social providers for account existence
how to go about creating this complex type of flow in Azure AD B2C custom policies.
Any pointers in the right direction would be greatly appreciated
Not possible. Nobody would allow you to probe a social IdP for an email. Data protection etc.
Reference our samples and wiki
Your sign up would be from our default sign up journey.
Your sign in flow could work like this:
Request for email
Read the directory to see if an email exists
If email exists, send the user to the IdP they used to sign up. You can do that by looking at the “issuers” registered on the userIdentity object,
If email doesn’t exist, send the user to the combined sign in and sign up page (technical profile) where they can sign in with social or sign up with a local account. Hide the sign in elements with CSS.

How to skip the login screen if user is not pre logged in but authorized the azure app in past

I have created an Azure app. After granted permission by user(once in lifetime ), my Azure+JS code fetches the users' outlook mailbox data with help of graphAPI+accessToken.
The Microsoft account is part of my org(office365). So when I go to my website(which is using the APP plus JS code to send graphAPI).
If the user is pre logged-in, I have suppressed the extra login-page.
Refer how to suppress the login screen in Azure AAD authentication Thanks #juunas
But if the user is NOT pre logged in to the office365 account, user is redirected to the office365 login. I do not want my user to see this login page each time when user is not pre-logged-in. The user has authorised this app and this wont be a good user experience though.
I have gone through the docs, which says this is possible through ADAL.js.But I coudnt find my exact use case there. Could some one explain/direct me to the correct answer for my problem?
