Sign up and sign in to Fly.io

If it’s your first time using Fly.io, you’ll need to create an account. To sign up, run:

fly auth signup

This will take you to the sign-up page where you can use your email address, your Google account, or your GitHub account to create a Fly.io account. When you sign up with GitHub, we’ll send you a confirmation email with a link to set a password; you’ll need a password so we can actively verify that it’s you for some Fly.io operations.

Note: At some point, you’ll be prompted for credit card payment information. New accounts start on our Pay As You Go plan. See Pricing and Billing for more details.

After signing up you’ll be returned to your command line, ready to use Fly.io. If you already have a Fly.io account, all you need to do is sign in with flyctl. To sign in, run:

fly auth login

When your browser opens to the Fly.io sign-in screen, enter your user name and password to sign in. If you signed up with GitHub, then click Sign in with GitHub to sign in. After logging in you’ll be returned to your command line, ready to use Fly.io.

Microsoft WSL users may need to run the following command, which creates a symbolic link that allows the browser to open:ln -s /usr/bin/wslview /usr/local/bin/xdg-open

⌘I
