Re: microsoft authentication app

Your note 2 is probably too old and incompatible.
Your 2 options are get a new phone or try to find the app on Google and sideload it.

Re: microsoft authentication app

I think KK 4.2 was the last os update on the Note 2 from memory of owning one so yes no easy answer I'm afraid. I think maybe if you need to access work emails your only option would be to treat yourself to an upgrade. Shame really because the Note 2 is a damn good phone.

There is always the old Microsoft Account App, which Authenticatior replaced.




That should work but you probably have to install it from a laptop and uncheck the unknown sources button, with the usual caveats about doing so at your own risk.
