Password word problem: Can not access OneNote anymore.

Using Windows 10 and Chrome Browser.
This involves Hotmail, OneDrive, OneNote.
---------------------------------------------
When accessing my Hotmail yesterday, MS notified me that there was suspicious activity that someone tried to login my email account and advised me to change the PW. I did it.

Today when I turned on my computer, It said that I failed to login to OneDrive (I did not try to access OneDrive to begin with, I just powered up my computer). It asked me to login.
I typed in the New PW that I just established yesterday. It took it, but asked me to change the PW again (I just did it last night). So, I changed the PW again (because OneDrive asked me to change.)

Now I can not access MS OneNote. OneNote doesn't recognize the new PW. Please help.

Sure appreciate very much.

After changing the PW for Hotmail (advised by MS to do this). Power-up the computer the next day, Onedrive asked me to change PW, so had to change OneDrive and Hotmail (and thus for hotmail again).
Now unable to access OneNote, and unable to post a question to Microsoft community (intended to ask how to access OneNote).

Looks like the Hotmail, OneDrive, OneNote, & MS community (login to ask questions): All use the same PW.
The change of PW in one place is not recognized by other places.
(OneNote and MS community login - do not give me a chance to enter the new PW that I changed yesterday for Hotmail & OneDrive.)

So, I am unable to access OneNote (except through hotmail/OneDrive), and unable to post a question to ask the MS community.

Re-phrase my question:

After changing the PW for my hotmail (advised by MS to do this), I am unable to access OneNote and unable to post a question to the MS community - neither place allows me to enter the just changed PW.
Thanks in advance for your help.

Hi, I had this same problem and none of the answers I found helped me and I was extremely concerned because I had data stored in the OneNote app that I couldn't find!
On Windows 10, I solved it by verifying some user account nonsense outside of OneNote.
1. Go to Start->Settings->Accounts->Your email and accounts
2. There was a note there asking me to verify my account.
3. After clicking the link, I entered in my Microsoft account password.
4. I went back and re-started the OneNote app and came up with no error.
I have to wonder why this suddenly came up? Was there some Windows update that caused this.
