The above error can come when you are doing an operation in your Heroku account from a different machine (other than the one you had used to log-in for the first time). The Heroku log-in generates a public key on the very first log-in attempt. Now, each client that needs to log-in to Heroku, must generate a public key. Since it does not happen automatically on subsequent log-ins, it needs to be done manually for each machine that you intend to use to operate your Heroku account from.
This is how you can generate a public key and add it to your Heroku account
$ ssh-keygen -t rsa
$ heroku keys:add
The first command would generate a public key. And, the second one would add it to your account. You can see all the keys added to your Heroku account by:
$ heroku keys
