While trying to create a new web application from SharePoint 2013 central administration site, It gave this error message:
Sorry, something went wrong
The password supplied with the username Domain\Username was not correct. Verify that it was entered correctly and try again.
This issue arises when the SharePoint 2013 farm account’s password is expired or changed!
Update SharePoint Farm Credentials! Here is how to update SharePoint 2013 farm credentials using STSADM tool:
stsadm -o updatefarmcredentials -userlogin <UserAccount> -password <New-password>
stsadm -o updatefarmcredentials -userlogin Crescent\SP13Farm -password “Password-of-the-Account”
Once you receive the message “Operation completed successfully.”, Restart IIS!
