Allow authentication to Azure functions with accounts that have MFA enabled.
Currently, if you use functions as middleware for a non-authenticated client app (like wasm blazor), there is no way to authenticate to a function middleware layer if your account is MFA enabled. This could be either a) having some kind of ms auth phone-like app connection to do the auth or 2) to do pre-auth like is done with logic apps and some of the connectors (e.g. twitter).
I think this could take any of a number of forms, but is definitely a current limitation when integrating serverless applications.
It’s unclear exactly what is breaking in the example scenario. MFA as a feature of AAD can work here, especially if the public client is using one of the identity SDKs for login. Is this specific to a given provider, or more around a general pattern?
There are patterns in Durable Functions for dealing with human interaction flows if looking to build your own MFA flow: https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-overview?tabs=csharp#human
