Customize Sitecore Login Message

Sitecore displays error message to the user on login page , if authentication fails. During production window or any other uncertain condition , we might want to restrict all the content authors from login to Sitecore except admin and display our own custom message like – “Production deployment window. Please try after some time.” For the same we can provide checkbox option to admin to restrict or allow content authors to login to Sitecore.

Follow steps –

1. Create new dictionary item under item /sitecore/system/Dictionary/ in core database for error message.
