Hotmail keeps asking for my password.

Hotmail keeps asking for my password. My password was correct. I still changed it. It keeps asking for my password nevertheless. Not only is it very annoying but it also keeps me from using my iPhone properly because that pop-up blocks me all the time I have read some of the answers you have given to people with the same problem. You only answer by asking questions. Every time they answer your question you ask another question. So no answer to be found anywhere. Just more and more questions. If you have to ask me questions, please ask them all at once. I really don’t have time for ping-pong. Thank you.
