It's been maybe 3 years since I last used git. And it feels like, "hello, world" as I try to relearn the workflow.

The plan was to push a repository for my notes in Github when I encountered the following error message. This was resolved by connecting with SSH.

remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.

Connect with SSH

1. Generate new SSH key

   ssh-keygen -t ed25519 -C "your_email@example.com"
   

2. Copy the SSH key to clipboard

   pbcopy < ~/.ssh/id_ed25519.pub
   

3. Go to Github -> Settings -> SSH and GPG Keys -> New SSH Key
4. Set the Title and paste the SSH key
5. Add SSH key
