@cyanogenic If you load up the console for the cloudron app, you can manually access the DB using the mysql command - I forget the syntax to sign in as there are environment vars that are needed to do so.
Using the ID can allow people to get a very good sense of how many users are on the system and the amount of contacts. It also is information leakage because I know all the URLs for every contact.
I think using a hashid based on the contact id, the user creating it and maybe another factor would work great.
