    The best way to avoid such errors is to use one public/private key pair and not an extra key for heroku. This way you (or your system) can’t choose a wrong key to login in heroku.

    If you need more than one key pair on your system, you can set one key for heroku. This is done through the following command:

    heroku keys:add
