These are private id_rsa , and public id_rsa.pub keys. |*=o will create two keys in the ~/.ssh folder. SHA256:TAS8DyOa8vKITV0R4HP1PHM7aQ6wLMqZmgq7lJYfDgQ key's randomart image is: Your public key has been saved in /home/ubuntu/.ssh/id_rsa.pub. Your identification has been saved in /home/ubuntu/.ssh/id_rsa. You will see a screen like this ssh-keygen -t rsaĮnter file in which to save the key (/home/ubuntu/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): You can also enter a password, but we will not activate the password in this study. When the command is entered, press enter key for all options. To to do so, go to your terminal and type ssh-keygen -t rsa To create the SSH key, you can follow these steps git/config file, git will not ask for authentication anymore.įourthly, a new SSH key can be added to your GitHub account and be used for authentication. Url = entering the token to the URL in the. git/config file in the repository by placing the token between and cat. You can use the token when cloning like this git clone you have already cloned the repository, then you can update the URL in the. After this, the token can be used at the git URL as in the first option. These are the steps to create the token successfully. For security reasons, after you navigate off the page, you will not be able to see the token again. Step 7: Finally, click the Generate token button to generate the tokenĬlick the copy to clipboard icon to copy the token to your clipboard. To use your token to access repositories from the command line, select repo. Select the scopes, or permissions you’d like to grant this token. Step 6: Give your token a descriptive name. Step 5: If prompted, confirm your GitHub password. Step 4: In the right-upper corner, click Generate new token Step 3: In the left sidebar, click Personel access tokens. Step 2: In the left sidebar, click Developer Settings Step 1: In the upper-right corner of any page, click your profile photo, then click Settings You can also follow the same step from the git documentation. To create the token, you can follow these steps Thirdly, a token can be created at the repository and be used for authentication. If you would like the daemon to exit early, forgetting all cached credentials before their timeout, you can issue an exit action: git credential-cache exit $ git config -global credential.helper 'cache -timeout=86400' You can overwrite the default as follows, for example, for one day ( 1 day = 24 hours × 60 minutes × 60 seconds = 86400 seconds) $ git config -global credential.helper 'cache -timeout=86400' When this time elapsed, git will force you to enter your username and password again. Password for up to time unit for the cache is in seconds and default is 15 minutes. $ git config -global credential.helper cacheĪgain, in the first interaction with the repository, the credentials are retrieved from the user and stored in the cache as follows: git config -global credential.helper git pull To activate this $ git config credential.helper cache cat can also store the credentials information in the memory for a certain amount of time. The file is protected only by standard user file permissions. Password for up to ~/.git-credentials checked, the credentials are stored as unencrypted. $ git config -global credential.helper storeĪfter that, on the first interaction with the repository, the credentials are retrieved from the user and stored as follows: git pull To activate this option, $ git config credential.helper store The store option saves the credentials in a file named as ~/.git-credentials for each URL context. Secondly, you can use the credential.helper to store or cache the credentials. Url = +refs/heads/*:refs/remotes/origin/*Īs you see, the credentials information exposed in command history and also not encrypted in the file, and only protected with routine user file permissions. To clone the repo without the username and the password authentication, enter those values to the link as follows: git clone you already cloned ar checked out the repo, go to the path-to-repo/.git/config file and update URL accordingly with the username and the password . To clone a repository, go to the repository, click the Code, and then copy the link by clicking the copy to clipboard icon as follows: Let’s take a look at these options and briefly discuss them.įirstly, when cloning the repository, you can enter the username and the password to the clone link. There are come workarounds or ways to get rid of entering the credentials, namely username-password, each time to interact with the repositories. However, when working with these repositories’ private instances, it is very annoying and boring to enter the credentials at each code interaction attempt. The authentication to access the source code repositories like GitHub, GitLab, Bitbucket, etc., is crucial.
