# How to authenticate with GitHub using SSH
|
||
|
|
|
||
|
|
Check that there are no `rsa` files here before continuing, use:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
ls -al ~/.ssh
|
||
|
|
```
|
||
|
|
|
||
|
|
If there is nothing to list (i.e. `: No such file or directory`) then use:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
mkdir $HOME/.ssh
|
||
|
|
```
|
||
|
|
|
||
|
|
If there's nothing there then generate a new keygen with:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
ssh-keygen -t rsa -b 4096 -C your@email.com
|
||
|
|
```
|
||
|
|
|
||
|
|
Now using `ls -al ~/.ssh` will show our `id_rsa.pub` file.
|
||
|
|
|
||
|
|
Add the SSH key to the SSH agent:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
eval "$(ssh-agent -s)" # for mac and Linux from bash
|
||
|
|
```
|
||
|
|
|
||
|
|
```shell
|
||
|
|
eval `ssh-agent -s`
|
||
|
|
ssh-agent -s # for Windows
|
||
|
|
```
|
||
|
|
|
||
|
|
Add RSA key to SHH with:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
ssh-add ~/.ssh/id_rsa
|
||
|
|
```
|
||
|
|
|
||
|
|
Copy your key to clipboard
|
||
|
|
|
||
|
|
```shell
|
||
|
|
clip < ~/.ssh/id_rsa.pub # Windows
|
||
|
|
```
|
||
|
|
|
||
|
|
```shell
|
||
|
|
cat ~/.ssh/id_rsa.pub # Linux
|
||
|
|
```
|
||
|
|
|
||
|
|
Go to your GitHub [settings](https://github.com/settings/keys) page and click the 'New SSH key' button paste in your generated key.
|
||
|
|
|
||
|
|
Then authenticate with:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
ssh -T git@github.com
|
||
|
|
```
