Apple's Keychain and Keychain Access have been integral parts of macOS for securely
storing and managing passwords, encryption keys, and other sensitive information.
Here's an overview of their historical and present usage:
Keychain
The Keychain is a secure storage system introduced in macOS (previously called Mac
OS X) to store passwords, encryption keys, certificates, and other sensitive data. It uses
robust encryption to protect this information, which can only be accessed with the user's
login password or a specific keychain password.
Keychain Access
Keychain Access is a macOS application that provides a user interface for managing
the various keychains on a Mac. It allows users to view and edit the contents of their
keychains, including passwords, certificates, and secure notes. Keychain Access has
been a part of macOS since its early versions, providing a convenient way for users to
manage their sensitive information.
Historical Usage
The Keychain system and Keychain Access app have been integral components of
macOS since its inception. They have evolved over time to enhance security and
functionality:
1. Early Versions: In the initial releases of Mac OS X, Keychain Access was a basic
tool for managing passwords and encryption keys.
2. Improved Security: With each subsequent macOS release, Apple has
strengthened the security of the Keychain system, introducing features like access
control lists (ACLs) and better integration with other Apple services.
3. iCloud Keychain: With the introduction of iCloud Keychain in macOS Sierra
(2016), users could sync their passwords, credit card information, and other secure
data across their Apple devices.Present Usage
In the latest versions of macOS, Keychain and Keychain Access continue to play a
crucial role in password management and secure data storage:
1. Password Management: Keychain Access stores passwords for websites,
applications, and services, allowing users to autofill login credentials securely.
2. Secure Notes: Users can store encrypted notes, such as credit card information or
secure documents, within their keychains.
3. Certificate Management: Keychain Access manages digital certificates used for
secure communication and authentication.
4. iCloud Keychain Integration: iCloud Keychain synchronizes passwords, credit
card information, and other secure data across a user's Apple devices, ensuring
seamless access.
While the terminology and specific features have evolved, the core functionality of
Keychain and Keychain Access remains essential for macOS users to securely store
and manage their sensitive information across devices and services.
Creating a New Keychain:
When you create a new keychain using Keychain Access, it serves as an additional
secure storage location separate from the default keychains. To create a new keychain,
right-click in a blank part of the left sidebar of Keychain Access and select an option
(new or add) from the menu.
The main reasons for creating a new keychain include:
1. Separate Password: You can set a different password for the new keychain,
distinct from your user account password. This can provide an additional layer of
security if your user account password is compromised.2. Selective Access: You can control which applications or services have access to
the new keychain, allowing you to isolate sensitive information and grant access
only to specific applications.
3. Backup and Portability: New keychains can be easily backed up, copied, or
transferred to other Macs, providing a convenient way to manage and share
specific sets of credentials or secure data.
4. Organization: Creating multiple keychains can help you organize your sensitive
information based on different categories or purposes, such as separating work-
related credentials from personal ones.
While the default login and system keychains are essential for storing and managing
your day-to-day passwords and credentials, creating additional keychains can offer
more flexibility, security, and organizational benefits, depending on your specific needs.
1. Selecting "New": When you choose "New" from the "File" menu in Keychain
Access, it allows you to create a brand new keychain file. This is essentially a
separate container or database that can store passwords, certificates, and other
secure items independently from your existing keychains. You can create a different
password for each Keychain or use the same password used to log in. All Keychains
are stored in ~/Library/Keychains (where “~” is the user’s Home directory).
Creating a new keychain is useful when you want to:
• Organize your secure items into different logical groups or categories.
• Set a different password for the new keychain, separate from your login or
system keychain.
• Share or transfer a specific set of secure items with others by providing them
with the new keychain file.
2. Selecting "Add": When you choose "Add" from the menu, it allows you to add a
new secure item (like a password, secure note, certificate, or key) to an existing
keychain that is already open in Keychain Access.
Adding a new item is useful when you want to:
• Store a new password, secure note, or other sensitive information in your login
or system keychain.
• Add a new certificate or encryption key to an existing keychain for authentication
or encryption purposes.
• Organize your secure items within the same keychain by creating categories or
folders.
In summary:"New" creates a brand new keychain file, which acts as a separate container for storing
secure items.
"Add" allows you to add new secure items (like passwords, notes, certificates) to an
existing keychain that is already open and accessible in Keychain Access.
The choice between "New" and "Add" depends on whether you need to create a
separate keychain for organizational or sharing purposes, or if you simply want to add
new secure items to an existing keychain that you're already using.
The Proposed Apple Passwords App
Apple is set to introduce a new standalone app called "Passwords" that aims to
enhance and streamline the password management experience across its ecosystem of
devices and platforms.
Key Features and Functionality
Unified Password Manager:
The Passwords app will serve as a centralized hub for managing all your saved
passwords, passkeys, and verification codes across Apple devices, including Macs,
iPhones, iPads, and even the upcoming Vision Pro headset.
It will replace the current method of accessing passwords through individual app
preferences or system settings.
Cross-Platform Synchronization:
Passwords will sync seamlessly across macOS, iOS, iPadOS, and Vision Pro devices
using iCloud Keychain.
Notably, it will also sync with Windows PCs via the iCloud for Windows app, expanding
password management capabilities beyond Apple's ecosystem.
Improved Organization and Accessibility:
The app promises better methods for organizing and accessing your saved passwords,
logins, and other secure information.
It aims to provide a more user-friendly interface compared to the current iCloud
Keychain experience.
Security Alerts and Recommendations:
Passwords will likely incorporate security features like compromised password alerts
and recommendations for improving password strength and enabling two-factor
authentication.
Passkey Support:In line with Apple's push for passwordless authentication, the Passwords
app will support managing and using passkeys, which leverage public-key
cryptography for secure sign-ins.
Potential Benefits
1. Centralized Management: A dedicated app for managing passwords across
devices can streamline the user experience and make it easier to access and
update login credentials.
2. Cross-Platform Accessibility: Extending password synchronization to Windows
PCs addresses a long-standing limitation and caters to users who operate in multi-
platform environments.
3. Enhanced Security: Features like security alerts, recommendations, and passkey
support can help users maintain better password hygiene and adopt more secure
authentication methods.
While the Passwords app is still in development, it represents Apple's commitment to
improving password management and security for its users across various platforms
and devices.
