Introduction

Managing remote repository credentials is an essential aspect of working with version control systems. If you're using IntelliJ IDEA 14, you might need to change your remote repository authentication due to various reasons such as security policies, password updates, or switching to a new account. This article walks you through the process of altering these credentials within IntelliJ IDEA 14, offering technical explanations and practical examples along the way. We'll also summarize key points in a tabular form for quick reference.

Prerequisites

Before diving into the instructions, ensure that:

• You have IntelliJ IDEA 14 installed on your machine.
• You have access to the remote repository credentials or have recently updated them.
• You are connected to the internet, as some steps might involve online repository interactions.

Steps to Change Remote Repository Credentials

Step 1: Open IntelliJ IDEA

Start by launching IntelliJ IDEA 14 on your computer. Once opened, locate the project linked with the remote repository for which you need to update credentials.

Step 2: Access Version Control Settings

1. Go to File > Settings (or IntelliJ IDEA > Preferences on macOS).
2. In the settings window, navigate to Version Control > Git.

Step 3: Modify Repository URL

• If your credentials have changed due to a new URL or SSH key, update the repository URL in the Git settings.

# Example of changing the URL
git remote set-url origin <new-repository-URL>

Step 4: Clear Existing Credentials

1. Navigate to File > Settings.
2. Go to Appearance & Behavior > System Settings > Passwords.
3. Here, you might find options like In native Keychain or Do not save. Select Do not save temporarily if you need to clear cached credentials.

Step 5: Access the Remote Repositories Setup

• Within the Git settings, click on Manage Remotes to review the list of remotes. Here you can add, edit, or remove remote entries.

Using SSH for Authentication

If you prefer or need to use SSH for authentication (often considered more secure than HTTP), ensure your SSH keys are set up properly:

1. Generate a new SSH key if necessary:

    ssh-keygen -t rsa -b 4096 -C "[email protected]"

1. Add the SSH key to your SSH agent:

    eval "$(ssh-agent -s)"
    ssh-add ~/.ssh/id_rsa

1. Add the SSH public key to your remote repository account settings.

Configure SSH in IntelliJ IDEA

• Go to File > Settings > Version Control > Git.
• Under SSH executable, select the appropriate SSH client (native or built-in).

Troubleshooting

If after changing credentials the connection fails, consider these troubleshooting steps:

• Verify that the repository URL is correct and accessible.
• Double-check your username and password.
• Ensure that the SSH key is added to the SSH agent if SSH is used for authentication.
• Look into IntelliJ IDEA's event log for error messages that might provide additional context.
