Configure a Credential Helper (Git)

git_ssh_http.txt

To avoid entering your password each time you interact with a Git repository over HTTPS, you can configure Git to cache your credentials using a credential helper.
1. Configure a Credential Helper:
Caching in memory (temporary): This caches your credentials for a set period.
Code

    git config --global credential.helper cache
    git config --global credential.helper 'cache --timeout=3600' # Caches for 1 hour (3600 seconds)
Storing indefinitely (less secure): This stores your credentials on disk, potentially indefinitely. This is generally less recommended due to security implications.
Code

    git config --global credential.helper store
Using OS-specific credential managers (recommended for security):
macOS:
Code

        git config --global credential.helper osxkeychain
Windows.
Code

        git config --global credential.helper wincred
2. Verify the Configuration:
You can check if the credential helper is set up by running:
Code

git config --get credential.helper
Explanation:
Credential Helpers:
These are external programs or functionalities that Git uses to securely store and retrieve your authentication details (like usernames and passwords or personal access tokens).
--global flag:
This applies the configuration to all your Git repositories. If you want to configure it for a specific repository, omit this flag.
cache helper:
Stores credentials in memory for a specified duration, after which you'll be prompted again.
store helper:
Stores credentials in a plain-text file on your disk, which is less secure.
osxkeychain and wincred helpers:
Integrate with your operating system's secure credential storage mechanisms (like macOS Keychain or Windows Credential Manager), offering better security.
Note: While convenient, storing credentials always carries some level of security risk. Using SSH keys with an SSH agent for passphrase management is generally considered a more secure alternative for frequent interactions with remote repositories.
