Hi there. Your permission is needed for DIM to get access to read and display characters and inventory from your account. Removing authorization doesn't permanently stop the ability for you to give DIM authorization again. See [url=https://github.com/DestinyItemManager/DIM/wiki/Accounts-and-Login]this page[/url] on DIM's website and check their support page if you have questions about DIM. [quote]If you want to prevent DIM from being able to access your account at all (for example, if you gave your login info to someone else who now has access to your account), you need to go to Bungie.net's Account Linking page, and either de-authorize DIM, or revoke all companion app sessions. It may take an hour or so for the other sessions to truly be logged out, which is a Bungie.net thing.[/quote] Removing authorization and logging out of DIM are the only steps to take. After that you cannot use DIM unless you intentionally repeat the process to log in with one of your accounts and give DIM authorization again.
