Login one time for two applications MSAL angular

Question

Hello

I have two applications, APP A and APP B, these apps are angular project MSAL that use Azure AD B2C service.

If the user authenticates from APP A or APP B
then the page should show APP A Home or APP B Home respectively.

Is there any way to log in to an APP so that I can also be logged in to another APP?

Hi @Aldair Revilla

Based on how authentication works on Azure AD you cannot do that. Access tokens provided by Azure AD are created based on the application identification, more specifically the audience (aud), which should match the Application ID on Azure AD. So, in your scenario, App A and APP B would have different aud information as those are 2 different applications, for that reason there's no way to use the same access token for both applications.

The documentation below has more information about Access Tokens:
