Learn How to Change Passwords on Your Devices

Understanding Why Changing Passwords Matters

Your passwords are like keys to your digital life. They protect everything from your email account to your bank information, social media profiles, and personal files stored in the cloud. When you change your passwords regularly, you reduce the risk that someone unauthorized could access your accounts. According to the Cybersecurity and Infrastructure Security Agency (CISA), a federal organization that tracks security threats, weak or reused passwords account for a significant percentage of data breaches affecting individuals and organizations.

Changing passwords becomes especially important after certain events. If you suspect someone may have seen your password, if you've used the same password across multiple websites, or if a website you use has experienced a data breach, changing your password should be a priority. Even if nothing has happened, security experts generally recommend changing your passwords periodically—many suggest every three to six months for accounts containing sensitive information.

Different devices store passwords in different ways. Your smartphone keeps passwords in its operating system. Your computer may store them in your browser or in a password manager application. Your tablet works similarly to your smartphone. Understanding where your passwords live on each device helps you know where to look when you need to make changes.

The process varies depending on what type of device you own and what account you're changing. However, the basic steps follow a similar pattern across most platforms: locate the account settings, find the security or password section, enter your current password to verify it's you, create a new password, and confirm the change. This guide will walk you through these processes for the most common devices and accounts.

Practical Takeaway: Start by identifying which of your accounts contain the most sensitive information—email, banking, and healthcare accounts typically rank highest. Make a mental note to change those passwords first, before moving on to other accounts.

Changing Passwords on Windows Computers

Windows computers use a local user account password that controls access to your entire computer. This password is different from passwords for individual websites or online accounts, though you can link your Microsoft account to your Windows login for added features. To change your Windows password, you'll need to access your account settings through the Control Panel or the Settings app, depending on which version of Windows you're running.

For Windows 10 and Windows 11, the most common approach is to use the Settings app. Click the Start button in the lower left corner, then type "Settings" and press Enter. Once Settings opens, look for "Accounts" in the left sidebar. Click on "Sign-in options." In the main panel, you'll see a section labeled "Password." Click on the "Change" button beneath it. Windows will ask you to enter your current password first—this verifies that you're authorized to make this change. After entering your current password correctly, you'll be prompted to create a new password.

When creating your new password, Windows will show you requirements that your password must meet. Typically, this means using at least eight characters that include uppercase letters, lowercase letters, numbers, and symbols. For example, a strong password might look like "BlueSky@2024#Oak" rather than something simple like "password123." You'll need to enter your new password twice to confirm you've typed it correctly. After you click Next and then Finish, Windows will apply the change immediately.

If you use an older version of Windows or need to change a different account on your computer, the process is slightly different. Right-click the Start button and select "Run," then type "netplwiz" and press Enter. This opens the User Accounts window. Select the account you want to change and click "Reset Password." You'll need to know the current password for that account to proceed.

Keep in mind that if you forget your new Windows password, recovering access can be challenging. Some versions of Windows offer password recovery through your Microsoft account, but the process isn't always straightforward. Before changing your Windows password, consider writing it down in a secure location—such as a locked drawer or a password manager—so you can reference it if needed.

Practical Takeaway: After changing your Windows password, test it by signing out of your computer and signing back in with your new password. This confirms the change worked and helps you remember the new password.

Changing Passwords on Mac Computers

Mac computers use a system password that controls access to your entire machine, similar to Windows. Apple makes this process straightforward through the System Preferences or System Settings application. The exact location depends on your macOS version—newer versions use "System Settings" while older versions use "System Preferences"—but the concept remains the same.

To change your Mac password, start by clicking the Apple menu in the upper left corner of your screen. Select "System Settings" (or "System Preferences" if you have an older Mac). Look for "General" in the sidebar, though some versions place password settings under different headings. Once you find the appropriate section, look for "Users & Groups" or "Login Options." You may need to click a lock icon and enter your current password to make changes to these settings.

Click on your user account name in the list. You should see a button labeled "Change Password." Click it, and macOS will prompt you to enter your current password for verification. After confirming your identity, you'll see fields for your new password. As with Windows, you'll need to enter the new password twice to confirm you've typed it correctly. macOS may also provide a password strength indicator—usually shown as a colored bar or gauge—that shows how secure your new password is.

Macs running newer versions of macOS may require passwords to include a mix of character types. A password like "MountainView$Sunset88" would meet these requirements. Avoid using personal information that someone might guess, such as your birth year, pet's name, or street address. The best passwords appear random or use a phrase that only you would remember, like the first letters of a favorite song title combined with numbers and symbols.

One Mac-specific feature is the ability to use your Apple ID as an alternative to your computer password. If you've set this up, you can reset your Mac password using your Apple ID if you forget it. This provides a recovery method that Windows users might not have, making it slightly less critical to store your Mac password in writing, though doing so remains a good practice.

Practical Takeaway: Unlike Windows, Macs allow you to create a password hint that appears on the login screen if you enter an incorrect password multiple times. Consider creating a hint that you'll remember but others won't—something meaningful only to you, like "Fourth word of my favorite book."

Changing Passwords on Smartphones and Tablets

Smartphones and tablets running iOS (Apple devices) or Android (Samsung, Google, and other manufacturers) store passwords differently than computers. Rather than a single password protecting the entire device, these devices use both a device passcode and passwords for individual accounts—like your Apple ID or Google Account. Changing the device passcode and changing account passwords are separate processes, both of which are worth understanding.

For iPhone and iPad users, the device passcode is changed through the Settings app. Open Settings, tap "Face ID & Passcode" (or "Touch ID & Passcode" on older models), and enter your current passcode. Scroll down and select "Change Passcode." You'll be asked to enter your current passcode again for security, then create a new one. Modern iPhones default to six-digit passcodes, though you can choose to use a four-digit code, a custom numeric code, or a full alphanumeric password if you prefer stronger security. After entering your new passcode twice, the change takes effect.

Android device users follow a similar process but the exact path depends on their phone manufacturer. Generally, open Settings, look for "Security" or "Biometrics and security," and find the option for "Screen lock type" or "Lock screen." Tap this option and select "PIN" if you're using a numeric passcode. Enter your current PIN, then create a new one. You'll enter the new PIN twice to confirm. Some Android phones also offer the option to change your passcode directly through the notification shade by swiping down twice and accessing Quick Settings.

Separate from your device passcode, you should also know how to change your Apple ID password (for iPhone and iPad) or your Google Account password (for Android devices). These passwords control your online accounts and the services connected to your device. For Apple devices, open Settings, tap your name at the top, select "Password & Security," and tap "Change Password." You'll need to verify your identity using Face ID or by entering your device passcode, then create
