An awk solution (tested under openwrt):
awk -F: -v RS=, '$1~/"authToken"/gsub(""","",$2);print $2' file
RJ3fadfiasdUYBxF6z
Or for more precisely matching, use equal ==:
awk -F: -v RS=, '$1==""authToken""gsub(""","",$2);print $2' file
RJ3fadfiasdUYBxF6z
$1==""authToken"" functionally equals to $1~/^"authToken"$/ but is a lit bit faster.

An awk solution (tested under openwrt):
awk -F: -v RS=, '$1~/"authToken"/gsub(""","",$2);print $2' file
RJ3fadfiasdUYBxF6z
Or for more precisely matching, use equal ==:
awk -F: -v RS=, '$1==""authToken""gsub(""","",$2);print $2' file
RJ3fadfiasdUYBxF6z
$1==""authToken"" functionally equals to $1~/^"authToken"$/ but is a lit bit faster.

That's JSON file format. Do you have any tool that can parse JSON?

I'm doing this out of a bash script on an openwrt router, so I don't think so? Trying to keep it as light as possible. I'm a super newb.
