Setting up a Github and Bitbucket account on the same computer on Mac OS. Now with a guide for Windows 10.

Setting up github and bitbucket on the same computer (Windows)

Guide for Windows

mix3d asked for some help using this guide with windows so here we go. This was tested with Windows 10. Run all commands in Git Bash once it's installed.

Github will be the main account and bitbucket the secondary.

Git for Windows

  • Download and install Git for Windows
    • In the installer, select everything but decide if you want a desktop icon (2nd step)
