@JaredBusch said in Tenant disabling of Basic Auth cause OAUTH iPhone to break:

Disabling of Basic Auth should have done nothing.

If the security setting are changed on an account it makes sense to force users to reauthenticate. It might even be best practice.

I think it works the same on other providers.

But there should be some better mechanism regarding authentication in ios and android.

Let's see, on the list of companies I would not turn to for a "security" solution....

@JaredBusch Yup, and they want to do a audit of devices using a deployment tool that is not even a Microsoft one.

Thanks I'll give this a try today
