How to Change Your Password on a Phone (Android & iOS Guide)
Changing a password on your phone sounds simple — but the answer depends on which password you mean. Your phone holds several layers of security credentials, and each one lives in a different place. Understanding which password you're actually trying to change is the first step.
What Kind of Password Are You Changing?
This is the most important question to ask before you start tapping through settings. There are three main types of passwords people typically want to change on a phone:
- Screen lock password — the PIN, pattern, or alphanumeric code that unlocks your device
- Apple ID or Google account password — the credentials tied to your app store, cloud backup, and device ecosystem
- App or service passwords — passwords for individual apps like email, banking, or social media
Each one is managed differently, and mixing them up is the most common source of confusion.
How to Change Your Screen Lock Password
Your screen lock is the first line of defense on your device. It's set locally on the phone — not connected to a cloud account.
On Android
- Open Settings
- Go to Security (sometimes listed as Security & Privacy or Biometrics and Security depending on your manufacturer)
- Tap Screen Lock or Screen Lock Type
- Enter your current PIN or password to confirm identity
- Select your new lock type and enter the new password
Android manufacturers customize this menu significantly. Samsung, Google Pixel, OnePlus, and others all place these options in slightly different locations, but the path through Settings → Security holds across most versions of Android 10 and later.
On iPhone
- Open Settings
- Tap Face ID & Passcode (or Touch ID & Passcode on older models)
- Enter your current passcode
- Tap Change Passcode
- Follow the prompts to set a new one
iOS gives you the option to use a 6-digit numeric code, 4-digit code, or a custom alphanumeric code. A longer alphanumeric passcode is significantly harder to brute-force, which matters if physical device security is a priority for you.
How to Change Your Google or Apple Account Password 🔐
This is a different credential entirely — and it protects far more than just your phone. Your Google account (on Android) or Apple ID (on iPhone) controls your cloud backups, purchases, Find My Device, and account recovery options.
Google Account Password (Android)
- Open Settings
- Tap your Google account at the top
- Tap Manage your Google Account
- Go to the Security tab
- Under How you sign in to Google, tap Password
- Follow the verification steps and enter your new password
You can also do this from any browser at myaccount.google.com — the change syncs to your phone automatically.
Apple ID Password (iPhone)
- Open Settings
- Tap your name at the top of the screen
- Tap Sign-In & Security
- Tap Change Password
- You may be asked to enter your device passcode first
Apple requires your screen lock passcode as a local verification step before allowing account password changes — a deliberate security layer.
How App Passwords Work Differently
Individual apps — email clients, social platforms, streaming services — store their own login credentials separately. Changing your password for Gmail, Instagram, or your bank app doesn't happen through your phone's settings. You'll do it:
- Inside the app under Account Settings or Security
- Via the service's website in a browser
Once you change a password on the service side, you'll usually be signed out of the app on your phone and prompted to log back in with the new credentials.
Key Variables That Affect the Process
| Factor | Why It Matters |
|---|---|
| iOS vs. Android | Menus, terminology, and paths differ significantly |
| Android manufacturer | Samsung, Pixel, Xiaomi, etc. each customize Security settings |
| OS version | Older versions may label options differently |
| Biometrics enabled | Face ID or fingerprint may bypass the password prompt in daily use, but a password change still requires it |
| Two-factor authentication | Changing account passwords on 2FA-enabled accounts adds a verification step |
A Note on Password Strength 🔒
Whatever password you're changing, the same principles apply: avoid sequential numbers (1234, 0000), birthdates, or anything predictable. For screen lock PINs specifically, six digits offers meaningfully more protection than four. For account passwords, a long, unique passphrase — ideally managed through a password manager — reduces the risk of credential stuffing if that service ever experiences a data breach.
When You Don't Know Your Current Password
If you've forgotten your screen lock passcode, recovery options depend heavily on your device and OS version. Android may allow a Google account recovery if the feature is enabled; iOS requires connecting to a computer and using Recovery Mode if too many wrong attempts have locked the device.
Account password recovery always runs through the service itself — using a backup email, phone number, or recovery code you set up previously. This is why keeping recovery options current matters before you're locked out.
The right steps — and the right level of complexity — depend on which password you're targeting, which device you're on, and how your account recovery is currently configured. That combination is specific to your setup.
