I'm auditing our organization's JAMF account and each time I delete a user or user machine, 1Password asks if I want to save the login. There aren't any details in the login profile other than a long string of *********'s. This isn't only limited to deleting and removing users. It's most actions where I cause some sort of "Save" or "Update" within the webapp that trigger this.
I created a .gif of the event in Snagit. Hope this helps!
