Just about once/ week my iPad asks for my Apple password. I get a red exclamation point symbol in Message too. I put in my KNOWN password and it tells me my account is locked. From the Settings page, I choose to change password by email. I go to the email and put in the same password that I KNOW is correct and it accepts it!!! When I go to Message, there's nothing there to read. As I use other programs, it again asks for my password. There have been times when a new update is available, and that ends up being why it wants my password, I think. Jumping through hoops because it doesn't like my password when I type it in the first time is crazy. Is it doing this because I don't do the two-part authentication? It comes out of the blue and doesn't seem to have any purpose. Going back to the updates, how can my iPad install updates automatically, at night as it says it will do, if I have to go through all of this without any apparent reason? Likewise, how can it install updates if I had used the two-part authentication? Thanks for your help.
