Sites with passwords

I have a question about sites with passords. I have a few subscription sites where I go regularly, such as the Wall Street Journal. If I use the clip to devonthink, and save as markdown, when I go to my inbox, I only get part of the page and then asks me to sign-in. To avoid this problem I use the Devonthink Sorter, but I have to Highlight the whole article and paste it into it. In addition it changes the fonts which creates a problem when reading in DT. I change the fonts. Here is the question. Does anyone experiences this problem? is there a setting that I should activate? or does anyone has a different work flow for these sites? I appreciate the help… thanks,
