Google has enabled multiple sign-in with the use of Switch Account. YouTube also supports this ability to switch between accounts.
For Gmail
- Login to Gmail
- Click your full name or email address in the Google bar.
- From the dropdown menu, click Switch account or Sign in to another account...
For YouTube
- Click your username in the upper right hand side of the page
- From the dropdown menu, above sign out, click Switch account.
Once you're logged in to both accounts, you'll be able to go back and forth between them without having to log out and log back in with different accounts.
Assuming you have Python installed, you can use getyoutubecc, which is a Python script.
Execution is as follows
>> python getyoutubecc Akqkvx407c8
Then keep the video and .srt in the same folder and you should be able to play in VLC.
For a non-technical way try one of the conversion sites such as http://mo.dbxdb.com/, which will download the .srt within a zip.

Select the track from the zip file
![Select the track](https://i.stack.imgur.com/RuqPJ.png)
And then you should see the subtitles appear

For videos with multiple tracks you will have to dig in and save it from .xml to .srt manually, there isn't a ready made tool out there on the web

<VIDEOID>
is the id of your Youtube video.
For some videos, it appears necessary to specify the name of the subtitle track, as seen on the Youtube page of the video, as a third argument:
http://video.google.com/timedtext?lang=<LANG>&v=<VIDEOID>&name=<NAME>

Unfortunately, due to some young abuser who abused the translation system, YouTube has changed the rules. Under the new rules, contributed translations won’t be published to YouTube until the channel owner has manually approved them.
Hopefully, YouTube can figure out a smarter automatic publish mechanism later.
