Hi Iron Gonzo,
I'd bet real cash money that you won't find a Triumph Dealer that will let you use their Log In user name and password,
and even if they did I would be even more surprised if the Triumph system let you in,
as it will undoubtedly be linked and authorised to the Dealer's specific IP address,
and will recognise any "illegal" attempt to log in from an unauthorised computer.
What is it that you want to do though ?
There is the "DealerTool" device you can buy and use legitimately ...
This is a link to their Web site :
DealerTool for Triumph motorcyleswhere there is plenty of information about what the tool can do,
and which has also been discussed in another forum thread here :
TTSE Diagnostic Tool - Group Buy....
