You will be asked to enter your Heroku credentials the first time you run a command; after the first time, your email address and an API token will be saved to ~/.netrc
for future use.
It’s generally a good idea to login and add your public key immediately after installing the Heroku CLI so that you can use git to push or clone Heroku app repositories:
$ heroku login
Enter your Heroku credentials.
Email: [email protected]
Password (typing will be hidden):
Authentication successful.
You’re now ready to create your first Heroku app:
$ cd ~/myapp
$ heroku create
