Ugh. I know there are other ways to get Jira API keys, but I wish they made one that was as easy and straightforward to set up as the kind you're talking about.
(No, I don't want to make a real "App" to sell on a "Marketplace," or be involved with oAuth, or any other tenant. I just want an API key for my own tenant, that isn't specifically tied to me, so every automation I build won't break when I quit someday.)
I recently discovered service accounts do exist. Though it might be on the Atlassian level, not Jira specifically.
