Push to GitHub without a password using ssh-key

If it is asking you for a username and password, your origin remote is pointing at the HTTPS URL rather than the SSH URL.

Change it to ssh.

For example, a GitHub project like Git will have an HTTPS URL:

https://github.com/<Username>/<Project>.git

And the SSH one:

git@github.com:<Username>/<Project>.git

You can do:

git remote set-url origin git@github.com:<Username>/<Project>.git

to change the URL.

---

In case you are indeed using the SSH URL, but still are asked for username and password when git pushing:

git remote set-url origin git@github.com:<Username>/<Project>.git

You should try troubleshooting with:

ssh -vT git@github.com

Below is a piece of sample output:

...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_dsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ecdsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ed25519
debug1: No more authentication methods to try.
Permission denied (publickey).

I actually have already added the public key to GitHub before, and I also have the private key locally. However, my private key is of a different name called /c/Users/Yuci/.ssh/github_rsa.

According to the sample output, Git is trying /c/Users/Yuci/.ssh/id_rsa, which I don't have. Therefore, I could simply copy github_rsa to id_rsa in the same directory.

cp /c/Users/Yuci/.ssh/github_rsa /c/Users/Yuci/.ssh/id_rsa

Now when I run ssh -vT git@github.com again, I have:

...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Authentication succeeded (publickey).
...
Hi <my username>! You've successfully authenticated, but GitHub does not provide shell access.
...

And now I can push to GitHub without being asked for username and password :-)

Additionally for gists, it seems you must leave out the username

git remote set-url origin git@gist.github.com:<Project code>

---

As usual, create an SSH key and paste the public key to GitHub. Add the private key to ssh-agent. (I assume this is what you have done.)

To check everything is correct, use ssh -T git@github.com

Next, don't forget to modify the remote point as follows:

git remote set-url origin git@github.com:username/your-repository.git

---

You have to use the SSH version, not HTTPS. When you clone from a repository, copy the link with the SSH version, because SSH is easy to use and solves all problems with access. You can set the access for every SSH you input into your account (like push, pull, clone, etc...)

Here is a link, which says why we need SSH and how to use it: step by step

Git Generate SSH Keys

---

Like the other users mentioned, you must convert it from using HTTPS to SSH. I don't see an answer with an end-to-end solution. After setting up the ssh keys, do (on your local machine) :

$ git remote set-url origin git@github.com:username/your_repo.git  # Convert HTTPS -> SSH
$ ssh-add ~/.ssh/id_rsa_github    # add private github ssh key ssh-agent (assuming you have it already running)
$ git push

---

You did everything ok but git still asking by password, this worked for me, execute the next commando in your current project's path:

~ ssh-add -K ~/.ssh/id_rsaYourIdRsa

Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_rsaYourIdRsa in the command with the name of your private key file.

---

for using SSH you must use $ git remote add origin git@github.com:USERNAME/REPOSITORY.git instead of git remote add origin remote_repository_URL. you can check it with $ git remote -v, if you see 2 lines in the below format, it will work correctly:

origin git@github.com:username/repo-name.git (fetch)
origin git@github.com:username/repo-name.git (push)

---

Using the command line:

Enter ls -al ~/.ssh to see if existing SSH keys are present.

In the terminal is shows: No directory exist

Then generate a new SSH key

Step 1.

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

step 2.

Enter a file in which to save the key (/Users/you/.ssh/id_rsa): <here is file name and enter the key>

step 3.

Enter passphrase (empty for no passphrase): [Type a password]

Enter same passphrase again: [Type password again]
