ccollab login issue

When I try to run the command ccollab login <url> <username>, it throws an error saying my credentials are invalid, and to "please supply a valid password." I know that the password I am using is the correct one; I am able to log into Collaborator via the web using those same credentials. Others are having the same issue, but some time ago, it was apparently working for some people. Has anyone come across a similar issue? What was the solution? Thanks!
