Here’s how to turn off biometrics on an iPhone, plus some quick context and forum-style tips.

How to Turn Off Biometrics on iPhone

Quick Scoop

If you want your iPhone to stop using Face ID or Touch ID and rely on a passcode instead, you can fully disable biometrics in Settings, and you can also temporarily shut them off with a button shortcut for emergencies.

Step‑by‑step: Turn off Face ID / Touch ID completely

These steps apply to recent iOS versions (Face ID and Touch ID models).

  1. Open Settings.
  1. Scroll down and tap Face ID & Passcode (or Touch ID & Passcode on older/home‑button models).
  1. Enter your device passcode to access the settings.
  1. In the “Use Face ID For” or “Use Touch ID For” section, toggle off options like:
 * iPhone Unlock
 * iTunes & App Store
 * Wallet & Apple Pay
 * Password AutoFill
  1. To completely stop biometrics from unlocking the phone, make sure iPhone Unlock is turned off.

Once you do this, your iPhone will only unlock with your passcode, and Face ID/Touch ID won’t be used for purchases or password autofill.

Note: Some users in forums mention also checking Screen Time → Content & Privacy Restrictions to ensure Face ID/Passcode options aren’t being forced on or off by restrictions.

How to temporarily disable biometrics (for one unlock)

Sometimes you don’t want to change settings permanently, you just want biometrics off for the next unlock (for example, at a border check or protest).

Two common ways:

  • Side button + volume button
    • Press and hold the Side button and either volume button until you see the power/Emergency SOS screen.
* Do **not** slide to power off unless you actually want to shut down.
* Tap **Cancel** or just let the screen turn off.
* Next time you unlock, your iPhone will **require your passcode** and Face/Touch ID will be disabled until you enter it.
  • Rapid side‑button presses (Emergency SOS)
    • On many models, pressing the Side button 5 times quickly also disables Face/Touch ID and triggers Emergency SOS.
* You must quickly **cancel** the SOS call if you don’t actually want to call emergency services.

This method is popular in security and privacy discussions because law enforcement in some regions can compel biometrics but not necessarily your passcode.

Why people are turning biometrics off (2025–2026 chatter)

Recent forum and news‑style discussions highlight a few trends around “how to turn off biometrics on iPhone”:

  • Legal/privacy concerns
    • Users at protests or traveling across borders often disable Face/Touch ID ahead of time and rely on a strong passcode.
  • Paranoia vs practicality
    • Some commenters argue most people are overthinking it and that law enforcement rarely cares about ordinary users’ phones.
* Others counter that it’s still smart to understand how to quickly lock down your device.
  • Accidental unlocks / convenience
    • A few iPhone owners turn off Face ID because it unlocks too easily when someone holds the phone up to their face, or because of inconsistent recognition with masks or glasses.

Extra tips and cautions

  • Turning off all biometrics means your phone is secured only by your passcode. Choose a strong one (not 1234 or your birthday).
  • If you ever want biometrics back, just return to Settings → Face ID & Passcode / Touch ID & Passcode and toggle the features on again.
  • For quick “panic” lock, remember the button shortcut so you don’t have to dive into settings in a stressful moment.
