password sign in

HI
I just got back into Halo after a long time. Sense Halo 4
Question, Do I have to sign in every time I restart from day to day ?
Can I save password ?

Sign in to where?

When I start the Halo5 it says I have to sign out. So I do. Then it says, Who Are You, and says what is your password.
Enter my password and off I go. I hope there is a way to save password or ignore.
Do you know what I mean . It’s the game start up.

This sounds like an xbox issue, but I assume it only happens in H5.
Do you have more than one account on you console? And if so, does this issue happen with those other accounts?
