I was creating a web application on Sharepoint 2016 by using Central Administration and I got the following error, “The password supplied with the username <domain> was not correct.
Problem
I have created SharePoint 2016 Environment in CloudShare Account when this issue started for first time creation of web applications.
Solution
I used below the command line to update credentials and it was successful.
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\BIN>stsadm -o updatefarmcredentials -userlogin <domain\username> -password <currentpasswordofCloudShareA/c>
