Keychain Access is the primary tool for managing your stored passwords, certificates, and keys.
  2. Select the Correct Keychain: In the Keychain Access window, you’ll see a sidebar with a list of keychains. The most common keychain is “login,” which stores your user account passwords. However, you might have other keychains, such as “System” or “iCloud.” Select the keychain where you believe the password for GitHub or VSCode is stored. Choosing the correct keychain is essential to ensure you're looking in the right place for your password.
  3. Search for the Password: Use the search bar in the top-right corner of the Keychain Access window to search for the password you want to delete. For GitHub, you might search for “github.com” or “Git Credential Manager.” For VSCode, you might look for entries related to your Git accounts or specific extensions that store credentials. Accurate search terms will help you quickly locate the password entry you need to remove.
  4. Identify the Correct Entry: Once you've performed the search, you'll see a list of matching items. Carefully review the entries to identify the correct one. Pay attention to the “Kind” column, which indicates the type of item (e.g., “Internet Password,” “Application Password”). For Git and VSCode passwords, you’re typically looking for “Internet Password” entries. Double-check the account name or URL associated with each entry to ensure you select the right one.
  5. Delete the Password: After identifying the correct entry, right-click on it. A context menu will appear. Select “Delete” from the menu. A confirmation dialog will pop up asking if you’re sure you want to delete the item. Click “Delete” to confirm. This action permanently removes the password from your Keychain. Alternatively, you can select the entry and press the Delete key on your keyboard.
  6. Authenticate if Required: In some cases, you might be prompted to enter your macOS user password to authorize the deletion. This is a security measure to prevent unauthorized modifications to your Keychain. Enter your password and click “Allow” or “OK” to proceed with the deletion.
  7. Verify Deletion: After deleting the password, it's a good practice to verify that the entry has been removed. Search for the same term again in Keychain Access to ensure the entry is no longer listed. This step confirms that the deletion was successful and prevents future authentication issues with the old credentials.

Common Issues and Troubleshooting

Despite the straightforward process, you may encounter issues when deleting Keychain passwords. One common problem is that the delete option appears greyed out or doesn't work when you press the Delete key. This can be frustrating, but several potential causes and solutions exist.

Another issue is being unable to locate the correct Keychain entry. If you have multiple entries related to GitHub or VSCode, it can be challenging to identify the specific password causing problems.

  2. List Keychain Items: To find the specific item you want to delete, you can list all items in your Keychain using the following command:
    security find-internet-password -g -a <account_name> -s <server_name>
    Replace <account_name> and <server_name> with the appropriate values for the password you want to delete. For example, if you’re deleting a GitHub password, you might use your GitHub username for <account_name> and “github.com” for <server_name>. If you're unsure of the exact values, you can try listing all internet passwords using security find-internet-password -ga to find the relevant entry.
  3. Delete the Password: Once you’ve identified the correct item, you can delete it using the following command:
    security delete-internet-password -a <account_name> -s <server_name>
    Again, replace <account_name> and <server_name> with the correct values. You’ll be prompted to enter your macOS user password to authorize the deletion.

Using the security command-line tool can be an effective way to bypass issues with the graphical interface of Keychain Access and directly manage your Keychain entries.

Best Practices for Managing Your Keychain

Effective Keychain management is crucial for maintaining both security and convenience. Here are some best practices to help you manage your Keychain effectively:

1. Regularly Review and Clean Up Your Keychain

Over time, your Keychain can accumulate numerous entries, including old or unused passwords. Regularly reviewing and cleaning up your Keychain helps keep it organized and reduces the risk of using outdated credentials. Schedule time every few months to go through your Keychain entries and delete any passwords that are no longer needed. This practice improves security by removing potential vulnerabilities and makes it easier to find the credentials you need quickly.

2. Use Strong, Unique Passwords

Strong, unique passwords are the foundation of good security. Avoid using the same password for multiple accounts, as this can lead to a cascading security breach if one account is compromised. Use a password manager (like Keychain) to generate and store strong, random passwords for each of your accounts. A strong password should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols. By using strong, unique passwords, you significantly enhance the security of your accounts and reduce the risk of unauthorized access.

3. Enable iCloud Keychain Sync

If you use multiple Apple devices, enabling iCloud Keychain Sync can be a great way to keep your passwords consistent across all your devices. iCloud Keychain securely syncs your passwords, credit card information, and other sensitive data across your Mac, iPhone, and iPad. This means that if you change a password on one device, it will automatically update on your other devices. To enable iCloud Keychain Sync, go to System Preferences > Apple ID > iCloud and check the “Keychain” box. Using iCloud Keychain Sync simplifies password management and ensures that you always have access to your latest credentials on any device.

4. Be Cautious of Phishing Attempts

Phishing is a common technique used by attackers to steal your passwords. Be wary of emails or messages that ask you to enter your password on a website or application. Always verify the legitimacy of a website before entering your credentials. Phishing attempts often mimic legitimate login pages to trick you into revealing your password. If you receive a suspicious email or message, do not click on any links or enter any information. Instead, navigate directly to the website in question by typing the URL into your browser. By staying vigilant and cautious, you can protect yourself from phishing attacks and keep your passwords secure.

5. Regularly Back Up Your Keychain

While Keychain is designed to be reliable, it’s always a good idea to have a backup in case something goes wrong. You can back up your Keychain by creating a copy of the Keychain files. These files are typically located in the /Library/Keychains/ directory. You can copy these files to an external drive or a secure cloud storage location. Having a backup ensures that you can restore your passwords if your Keychain becomes corrupted or if you encounter any other issues. Regularly backing up your Keychain is a proactive step that can save you a lot of time and hassle in the event of a problem.
