Support for aquire token silently?

[ricsantos]

Hi, I am using the MSALAuthenticationProvider to authenticate my user, and after authentication I am able to successfully fetch the MSGraphBaseURL /me object. However, for each subsequent run of the request, the user is prompted via an alert and then a modal web view to Sign In again (although the sign in process is just tapping 'Continue').
Reading a quickstart guide on portal.azure.com, it advises to first acquire a token using applicationContext.acquireToken(with: parameters), and if a user has already signed in to request a token silently using applicationContext.acquireTokenSilent(with: parameters).
My questions:

Does this library support acquiring the token silently?
Does a token need to be acquired every app launch, or is it somewhat long lived?

Thanks

I've also noticed that this library https://github.com/AzureAD/microsoft-authentication-library-for-objc describes how to acquire the token silently.

Update: following the guide on https://github.com/AzureAD/microsoft-authentication-library-for-objc I added the following items:

• keychain access group
• LSApplicationQueriesSchemes
• application:open:url callback

Not sure if all 3 are required, but the requests now return without needing to sign in again 🎉

Hello @ricsantos

Thank you for reporting this. Storing the credentials in the keychain would be a welcome addition to this library. Adding this to our backlog.
