Hi @Vijay Simha,
Welcome to Atlassian Community!
You will have to contact your admin for Confluence, if you do not know who that is I would start by asking your IT help desk.
You ended up here on the community because of a link on the log in page, but this is a public community mainly made up of Atlassian customers and as such we do not have access to other customers instances.
It looks like you're new here. Sign in or register to get started.
