Sometimes the run is done by clicking a run button, like: and:
Try all of the above. They are working links.
So you should treat each run as if it is a new, unknown website that you have landed on after following a link on social media. Do not enter any passwords (even Ancient Brain passwords) into a run window. Do not type any sensitive data into a run window. Follow any links in it with caution. Watch out for it redirecting to another server. Read any user comments. Check out who wrote it.
Please report misleading or malicious Worlds and Minds to firstname.lastname@example.org and we will delete them.
However, some runs can have a limited form of "login" where they are associated with your account, and Worlds can use AB functions to save data on the server in your account. This is data linked to your use of that World (e.g. your position in a game, or some object you created in the World). The data is saved in files like this in your uploads directory:
/uploads/YOURID/_data.WORLDID.jsonThe run can later read back from that file. (In fact, any run can read that file. Like all your uploads, it is public.)
Here is the plan for whether runs are "logged in" or not:
|Run launch||Run properties|
You are logged in to 1st server
Run is launched from World page or Mind page or Edit page
You are not logged in to 1st server
Run is launched from other page (list of Worlds, search results)
Here is an example of a World with "save data" and "restore data" buttons when you run logged in.
