A couple of days ago i put my iphone 5s on the charger and went for a walk. Everything worked fine. When I came back I grabbed my phone and it kept asking me to sign in and password information for everything I had no issues with before; facebook, email, icloud, all apps. I could still make phone calls and received text messages. At first I thought I had been hacked but it doesn't appear so. I accessed everything on my desktop and changed all of my passwords. I went back onto my iphone and entered the new passwords for facebook and other apps and it appeared to be working. I had additional problems with my email as I had to re-enter my password for my windstream email to work. I can receive emails but I get errors sending emails. Everything works fine through my desktop and I confirmed the configuration setup on my iphone for incoming and outgoing servers. Has anyone else had this happen to them recently and how can I fix my email issues? Do I just need to delete my email account and add it again?
