The most common place to find passwords in iOS is in the Keychain Services. The Keychain is a secure storage system that allows you to store sensitive data, including passwords, credit card information, and other personal details. To access your Keychain, go to Settings > Accounts > Passwords & Security > Keychain.

iCloud Keychain

If your app requires a password that is stored in the Keychain on another device, you can use iCloud Keychain to access it. To do this, go to Settings > Accounts > Passwords & Security > Keychain Access > Sign in with Apple.

App Specific Passwords

If you are developing an app that requires a password and does not use Keychain Services, you can create an App Specific Password (ASP). An ASP is a password that is specific to your app and is stored in the device’s keychain. To create an ASP, go to Settings > Accounts > Passwords & Security > Keychain Access > App Specific Passwords.

Third Party Password Managers

If you are looking for a more secure way to store passwords, you can use a third-party password manager app. These apps allow you to securely store and manage your passwords, making it easier to remember them and access them when needed. Some popular password managers include LastPass, 1Password, and Dashlane.

Keeping Passwords Secure in iOS 18

Use Strong Passwords

When creating a password for your app or any other sensitive information, it’s important to use a strong password that is difficult to guess. A strong password should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using easily guessed information like birthdays or names of family members.

Use Two-Factor Authentication (2FA)

Two-factor authentication adds an extra layer of security to your accounts by requiring a second form of identification in addition to your password. This can include a code sent to your phone, email, or other device. To enable 2FA on your account, go to Settings > Accounts > Passwords & Security > Two Factor Authentication.

Regularly Change Passwords

It’s important to regularly change your passwords, especially for sensitive information like app credentials and iCloud accounts. This will help prevent unauthorized access to your accounts if someone gains access to your password. To change your password, go to Settings > Accounts > Passwords & Security > Change Password.

Avoid Storing Passwords in Code

When developing an app that requires a password, it’s important to avoid storing the password in the code. This can make it easier for hackers to access the password if they gain access to your app’s source code. Instead, store the password in the Keychain or use an App Specific Password.

Case Study: Keeping App Credentials Secure

Let’s take a look at an example of how you can keep app credentials secure using iOS 18. Suppose you are developing a social media app that requires users to log in with their Facebook account. To keep the user’s Facebook login information secure, you would store the password in the Keychain or use an App Specific Password.

When a user logs into your app for the first time, they will be prompted to enter their Facebook email and password. After they enter their information, your app can use the Keychain or App Specific Password to securely log them into their Facebook account. By using the Keychain or an App Specific Password, you are preventing the user’s Facebook login credentials from being stored in plain text within your app code.
