Yes, but if the computer has the software, it's usually possible to connect the remote and get in without knowing the user name and password. If that doesn't work, a call to their tech support department can result in cloning the account and letting you in, which I have used when making changes to remotes that were originally programmed by Best Buy (who doesn't give the log in info to their customers/the customers forget where they put the info).

Their Pro Portal is a great way to keep all of the client setups in one place and they have training info, as well.
