Git & GitHub SSH Setup Guide (Simplified)

A minimal, step-by-step guide for securely setting up Git with GitHub via SSH in Termux or any terminal.

1. Set Git Identity

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

2. Generate SSH Key

ssh-keygen -t ed25519 -C "you@example.com"
  • Press Enter to accept default file location.
  • Leave passphrase blank (optional).

3. Start SSH Agent and Add Key

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519

4. Copy Public Key

cat ~/.ssh/id_ed25519.pub

📋 Copy the output.

5. Add SSH Key to GitHub

  1. Visit: https://github.com/settings/ssh/new
  2. Paste your public key.
  3. Name it (e.g. Termux SSH).
  4. Click Add SSH Key.

6. Test SSH Connection

ssh -T git@github.com

✅ Expected:

Hi username! You've successfully authenticated...

7. Clone a Repo via SSH

git clone git@github.com:username/repo-name.git

📌 Done! You're now set up to use GitHub with SSH.
