After 4 years, I came back to programming.
And the first thing I did was try to run my old abandoned project.
Now, I was determined to complete it and share.
So started to complete the unfinished features and give them some final touches.
Once I completed one of the features, I saved the changes on git and tried to push it to Github repository.
Unfortunately I started getting some "Couldn't Connect" type errors.
And it said
You cannot connect git and github with username and password, it deprecated in 2021.
To fix this issue, I did some google search and found a good medium article and a YouTube.
Following those resources I found out that I needed to generate SSH key to connect Git and Github now.
So, I followed the these Steps to connect Git and Github with SSH Keys
1. Generate SSH Keys on My Mac 💻
To generate the SSH keys, I opened thee terminal and executed the following command
ssh-keygen -t Ed25519 -b 256
Once the keys (private and public) are generated, it'll ask for the location to save it.
You can save it in default location by pressing Enter.
Then you'll have to give a passphrase.
You can press Enter if you don't want to add it.
But it's recommended to add a passphrase.
Note: When you push to Github you may need to enter the Passphrase. So you need to remember it.
If you want to check or see the existing SSH keys, use the following command
ls -al ~/.ssh
2. Display the Public Key
After you generated the SSH keys, you need to copy it.
For that you can use the following command to display the public key
cat ~/.ssh/id_ed25519.pub
Then copy the displayed public key from the terminal.
3. Add the Public SSH Key to Github
Now, Log In to Github and then go to Settings and then to SSH and GPG Keys
Link: https://github.com/settings/keys
Then click on New SSH Key
Now, Give Title to your new SSH Key and paste the public SSH key that you copied from Step 2 👆 .
4. Activate SSH agent
Now, in your terminal you need to activate the SSH agent.
For that, use the following command
ssh-add
Hope it's helpful to you.
