Any relevant documentations for developing mobile client with Modern Authentication? RRS feed

  • Question

  • Hi folks,

    My situation is that I am investigating how to develop mobile client with Modern Authentication. Just ask around for any relevant documentations/posts about how to communicate between client app and the server for getting the token.

    I have an Office 365 domain. Is it enabled with Modern Authentication by default?

    Is Exchange Online related to what I want to do?

    Much thanks!

  • Yeah you'll be using modern auth ( aka Oauth2).

  • Thanks for your reply!!

    What I understood is when a mobile client supporting OAuth 2 adds an O365 account, by default the OAuth 2 (Modern Authentication) is used. Otherwise, Basic Authentication is the fallback. The O365 domain admins do not need to do any extra work to enable Modern Authentication.

    Am I correct? Thanks!

  • Well I'm a bit confused now, if you're developing a mobile client - it's up to you if you want to fallback with basic authentication. Though, if Oauth2 fails, I can't see a reason as to why basic authentication would work - apart from some edge cases.

    What I'd do if I was developing a mobile client and wanted a fallback - something along the lines of

    //Let's assume you already retrieved a bearer token in the token variable
    
    Result = BearerToken
    
    If (Result == null) 
    {
    //Fall back with basic auth and store the token somewhere
    }
    
    Else
    {
    // Carry on with your program, pass bearer token to Exchange online etc. 
    }
    
    With regards to if the O365 admin would need to do extra work to enable modern auth - nope. That's always enabled. However, your app might need an identity, read here - https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-integrating-applications
