• Go to Personal access tokens (in GitHub Settings > Developer settings)
• Select which repositories you'd like this token to have access to (Public, All, or Select)
• Create a token with the repo scope ("Full control of private repositories")
  • Alternatively, if working only with public repositories, select only the public_repo scope
• Copy the generated token
