No. I had Aegis set up originally, but I was only allowed a certain amount of log ins before I was forced to use the proprietary algorithm (which, being proprietary, Aegis doesn't support as it communicates with MS servers). Duo is better, it says "oh, no push notification? That sucks, just open the app manually". Authenticator won't work without push. I had to force my account to send me the code anyway by saying the app wasn't working for me.
