Microsoft Authenticator app offers a feature called Phone sign-in Microsoft Authenticator app offers a feature called "Phone sign-in" that allows for a more seamless and password-less authentication experience. With this feature enabled, you can sign in to your Microsoft account without having to manually enter your password
You are then presented with a number. The Authenticator app prompts you to authenticate by typing the appropriate number, instead of by entering a password.
After you have used passwordless phone sign-in once, the app then offers you this method as the default. You are always able to choose another method.
Follow the below link to find more about it and how to enable it.
