Way to dodge the one-time passwords

Technically, yes but it's a bit of a hassle to set up.

You'll need to use Microsoft's Application Compatibility Toolkit to apply shims to the launcher.

1. First, download and install both the Compatibility Toolkit and the Application verifier.
2. Run the Compatibility Toolkit's Standard User Analyzer Wizard . It is located in Start Menu > Microsoft Application Compatibility Toolkit > Developer and Tester Tools
3. Enter the location (or browse for) the launcher. It should be in C:\Program Files (x86)\Electronic Arts\BioWare\Star Wars-The Old Republic
4. Click Launch
5. Very Important: You should see 2 LUA Prompts: the first for the Standard User Analyser and the Second for the SWTOR Launcher. Accept the first but decline the second.
6. The Analyser will ask whether the application ran without problems. The launcher should not have launched (If it did, you may have accepted the LUA prompt I said to decline earlier). Click No
7. The Analyser will suggest some mitigations. You should only need to check Force Administrator Access (*), but if you want to be sure or if it doesn't work the first time, you can check them all; it will only loosen some security in a few extremely specific folders/registry keys. That should not cause any problem in an environment that allows you to play SWTOR.
8. Click "Launch" to test the settings.
9. The launcher should have launched properly without any prompts. If it didn't, click no and select somemore mitigations in step 7.
10. Once the launcher works properly, Click Yes then Export to create an msi file containing your fixes.
11. Run the generated MSI to install the shims permanently.

There is one last step to take care of every last prompt. In the extras folder of your SWTOR installation (so C:\Program Files (x86)\Electronic Arts\BioWare\Star Wars-The Old Republic\extras), there should be a file named vc2008redist_x86.exe. Rename it to vc2008redist_x86.exe.unused

(*) Despite the name, this shim does not give Administrator access to the launcher without your knowledge; it lies to the launcher telling it you are an Administrator when in fact you are not

There isn't a way to do that yet. However, there are a few things you can do to ensure your party doesn't spend all night waiting on the laggard:

1. Kick him from the party - It's by far the easiest solution, although the one that helps you least at the time. Bur for those people that can never seem to make to the meet up point on anything resembling time, it is the final solution.

2. Use your fleet pass - That eighteen hour cooldown is a bit of a b*tch, but it also means most people aren't in the habit of using it, so you can use it to meet at the fleet and roll out together, group already formed. you can even take the same ship as long as you let every one touch the door before the owner.

3. Speeder bikes for the win - The speeder bike network should get you close to any mission you might be running. Assuming that you have the network discovered in the first place that is... so always grab those first off.

All that said, even at low level, I haven't found any place that I couldn't get to in less than ten to fifteen minutes using a combination of the above tactics. It also helps to schedule stuff for specific times so that people can assemble without the originator standing around for all that time. If you do end up waiting, hey, at least you got some crafting time or something.
