Public links to files are off in every workspace until an owner or admin turns them on under Settings › Permissions, and guests can never make one. Turning the switch off stops every existing link at once, and admins can see and revoke the workspace’s live links. When retention deletes a message, its attachments and their links go with it. Removing a passkey asks for your password, a two-step code or a recent sign-in, and you get an email about it.
Deactivating a member disconnects their open sessions at once. In Kemble Work an incoming webhook stops posting while the person who added it is deactivated or gone, and starts again if they come back. On the website, moving between pages puts focus at the top of the new page, the security contact on /trust is a link, and the changelog’s month links are labelled and easier to press.
