So what I read everywhere is that, in order to connect to Salesforce via the API, you'll have to authenticate using OAuth.
But this involves creating a Connected App, which is 'cumbersome' for normal users. They just want to login and go.
How do e.g. Jitterbit and Mavensmate etc solve this? I don't install Jitterbit/Mavensmate in my org, do I? There's no connected app in my org. Yet, they can access my data when I provide my username and password+token.
How can I connect to Salesforce without running via OAuth and a Connected App or installing something in the org?
