I changed my password via the web interface. And now I can\'t run any command that requires authentication. Password is using plain ASCII, nothing fancy, no Unicode, weird non-p
I had the same issue on Windows Vista.
I got authorization failed messages on every heroku command and wasn’t able to login.
c:\Sites\jut>heroku login

I deleted
C:/Users/myusername/_netrc
where the passwords are stored.
After that I was able to heroku login
again and all went fine!
