Authentication with SSH Key

• Ran into problems with 2FA when trying to connect to my own repository despite trying out various methods using https and personal access tokens.

  • Username: Password => Failed

• Eventually was able to successfully authenticate my Github identity using an SSH key (Stackoverflow...Jossef Harush:

Generate new SSH Key with email as label

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Link key to Github account

• Use cat ~/.ssh/id_rsa.pub to output the generated public key, which should output something like:

ssh-rsa AAASDFlkajdsflkadsf23j23l4kjkalsdfja ... asdfkEWR== your_email@example.com

• Next go to https://github.com > Settings > SSH and GPG keys
• Click on "New SSH key", add a title and paste the key above into the box.

Change git origin from https:// to ssh

• Go to your repository location and type:

git remote set-url origin git@github.com:<github username>/<repository name>
