How do I generate new ssh-key for my new gitlab account?

Question

I have two Gitlab accounts. On my old account I added an ssh-key that is located in ~/.ssh/id_rsa.pub on my computer.

Answer 1

I would recommend a second key, for now without passphrase:

ssh-keygen -t rsa -C "your_email@example.com" -P "" -q -f ~/.ssh/gitlab_rsa

That will create (without any prompt) ~/.ssh/gitlab_rsa (private key) and ~/.ssh/gitlab_rsa.pub (public key)

You need to register that second gitlab_rsa.pub public key to your second GitLab account.

Navigate to the 'SSH Keys' tab in your 'Profile Settings'. Paste your key in the 'Key' section and give it a relevant 'Title'.

Then add a ~/.ssh/config file with:

Host gitlab_rsa
    HostName gitlab.com
    User git
    PreferredAuthentications publickey
    IdentityFile /home/<you>/.ssh/gitlab_rsa

Finally, you can clone any GitLab repo as your second identity with:

git clone gitlab_rsa:<yourSecondAccount>/<yourRepo.git>

That will be replaced automatically with git@gitlab.com:<yourSecondACcount>/<yourRepo.git> and will use your second key.

Answer 2

Generate SSH please follow below steps.

Open Git Bash on you machine

Enter the below command to genarate

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

Generating public/private rsa key pair. Enter a file in which to save the key (/c/Users/you/.ssh/id_rsa):Press enter Enter passphrase (empty for no passphrase): Type a passphrase Enter same passphrase again: Type passphrase again

Once enter the confirm passphrase, will get confirmation message.

go to the gitpair.pub file location and right click open with notepad. copy the code and past the in the below text box, your email will pick automatically in the title box. then click add key.

Answer 3

Generate a new key pair with:

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

It will ask you to enter a name for the key file:

 Enter a file in which to save the key (/home/you/.ssh/id_rsa): [Press enter]

Choose something different such as /Users/you/.ssh/gitlab_rsa

Then when you need it add this key to your ssh-agent with:

ssh-add ~/.ssh/gitlab_rsa

If you want a permanent access you can edit your ~/.ssh/config file with:

Host gitlab_rsa
    HostName gitlab.com
    User git
    PreferredAuthentications publickey
    IdentityFile /home/<you>/.ssh/gitlab_rsa

Refer to this article for further details.

Answer 4

You need to create the file ~/.ssh/config to define which key should use for every domain.

Create that file with nano and paste your configuration:

nano ~/.ssh/config

And add:

Host your-gitlab.com
    HostName your-gitlab.com
    IdentityFile ~/.ssh/your-gitlab-privkey
