Securely manage and autofill passwords across all your mobile devices with Microsoft Authenticator

Why are only the iOS screenshots available here? Are the Android steps the same as the iOS steps shown only with the iOS screenshots? Also, I have the Microsoft Authenticator app installed on my Android phone. I tested it to log in to certain apps and sites using my mobile device. How would a phone app help me log in to, for example, my T-Mobile Money online checking account using my Windows 10 Laptop either the Chrome or Edge browser when I sign in to my online checking account does it send an approval code to my Microsoft Authenticator app on my Android phone's app then when I approve it will sign me in to my online checking account's website via my computer automatically? BTW: As of 03/04/2025 there is no Microsoft Authenticator app Chrome Extension in the Chrome Web Store. I see that there is an Extension just called Authenticator App made by developmentbycores. However, I wasn't sure if it was safe or whether it was compatible with the Microsoft Authenticator app.

Thanks,
