prepopulating username field on Azure AD login

Question

When using Azure AD for authentication, does anyone know if it's possible to send the username as a parameter in the request to https://login.microsoftonline.com/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee so that this field is populated already in the login prompt?

Answer 1

Yes. You can specify the login_hint parameter.

For example:

https://login.microsoftonline.com/tenant-id/oauth2/[email protected]

Of course you need to include the other standard parameters as well.
