Repositories can only be created by logged-in users. Repositories may be created from several places within Bintray; a repository you create may be owned by you or by an organization of which you are a member.
To create a new repo:
Note: You can create a repo from several alternative places within Bintray. The New Repository button appears in the Owned Repositories work area of your user profile and also in the Repositories form of the Edit Your Profile page when editing your profile. If you are a member of an organization (and have the proper authorization), you can also create a new repo from the Organization Profile page. A repo created from within an organization is owned by the organization (for all other ways to create a repo, you are assigned ownership of the repo).
