Publish Online customisable url

Take a look at tinyurl.com of bit.ly.com, you sill still have and see the long url but you can direct readers to a simpeler one; you can also create your own bit.ly url if you register.

The "long string" is a UUID, which has so many possible combinations it is unfeasibly difficult for anyone to scan through them all to find everyone's documents. The UUID is the only "security" system for Publish Online - Adobe for some reason doesn't want to implement a login-to-view system like all the other providers do, so there cannot be options to make the URLs any more easily-guessable. If you were allowed to use "/view/secretfile1" then it's pretty much guaranteed someone else will try the same string, find it's already taken and immediately go read your document.

The simplest option to make things "easier" to type is to put the original URL through a shortener service such as bit.ly - their character sequences are of course much easier to scan through so there's a slight chance someone else could stumble upon it, but with millions of active sequences it's very unlikely anyone will try to visit every working link they find.
