I mean, look at the logos - they all were designed to mimic as closely as possible Microsoft Authenticator and Google Authenticator, just waiting to pounce on those that didn’t look close enough and installed the app. I can personally recommend that you install one of the reputable authenticator applications - Microsoft Authenticator and Google Authenticator. In Android’s case, it was hilarious to see that some other wannabe authenticator app almost entirely ripped off the official Google Authenticator icon (before it changed) and still made it through the review process.
