why do I have to put my email address in every time to sign in to my emails instead of just putting in my password even when I check the keep me signed in tab

cannot delete contacts on messenger , it is infected and sends vile messenges without me signing in

 

I received a text message proporting to be Microsoft giving me a password reset 7 digit code.   I also received a "Twitter" reset request in my hotmail account. Since I never requested a password reset and do not have a twitter account, what is going on?

I have been on the phone with Apple and they cannot figure out why I cannot receive a verification notice for Facetime on my hotmail account.  They
suggested I write you to see if there is something blocking the notification.
