Login constantly through office 365 when using Sharepoint

I have Workstations here are Win 10 Pro and office 365 in which I use MS Sharepoint and MS Dynamics.

Often when using these I use google chrome as the browser and often I am asked to sign in with my office 365 account this may happen 5 times a day.  
One of the staff at site say if you want to open a word doc and don't want to get prompted by sign in just open a blank document before hand and it works.  
Is there a way to correct this.  I have tried to add an entry into the credential manager and turning off local firewall.  I do know it does work most of the time through MS Edge.
But most staff like chrome.

Cheers :)

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Make sure to select the "keep me signed in" option when logging in, this will reduce the number of prompts. Alternatively you can configure some form of SSO, such as AD FS or AAD Connect SSO: https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnect-sso
