Apologies, I am perplexed. Has something changed with how API calls are handled in the past year. I had code that was working but now I get the above error. Has there been a URL change or perhaps formatting? I am using "3-legged OAuth flow authorization code" Thanks, Andy

What is your app platform type? Check this old thread to see how to change/fix your issue.

The change for that platform type is that it will no longer support password flow. However, you said that you have problem to login with 3-legged OAuth and you app is an old app? Please confirm and give me your app client id so I can check for you.
