You usually can’t reset Face ID when iOS thinks doing so would weaken your security or when there’s a restriction or hardware problem on the device.

Why you can’t reset Face ID (Quick Scoop)

1. Most common reason in 2025–2026: Stolen Device Protection

On recent iOS versions, if Stolen Device Protection is turned on, the “Reset Face ID” button can appear greyed out or unresponsive.

This is by design: the feature tries to stop a thief from wiping your Face ID and adding their own face. What typically happens:

  • “Reset Face ID” is greyed out or doesn’t react when tapped.
  • Other Face ID changes may also seem locked.

How people are fixing it (from recent guides):

  1. Go to Settings → Privacy & Security.
  1. Tap Stolen Device Protection.
  2. Turn it Off (you may be asked to authenticate with Face ID / passcode).
  1. Go back to Settings → Face ID & Passcode and try Reset Face ID again.

If the option becomes clickable after this, the issue was a security restriction, not a bug.

If you’re worried about turning this off: you can usually turn Stolen Device Protection back on after successfully resetting and re‑setting up Face ID.

2. Other software or profile restrictions

Even if Stolen Device Protection is off, device management profiles or internal restrictions can block Face ID changes.

Typical situations:

  • Work or school iPhone with a management profile installed.
  • “Reset Face ID” is greyed out, and you also can’t change other security settings.

Things that often help:

  • Check for profiles: Settings → General → VPN & Device Management.
    • If you see a company/school profile, it may be enforcing restrictions on Face ID.
* You’ll usually need your IT admin to remove or change that policy.
  • Make sure iOS is updated: Settings → General → Software Update.
* Apple sometimes fixes Face ID bugs in newer versions.

If you recently installed any configuration profile (beta software, work email, etc.), that could be the cause.

3. System glitches and basic fixes

Sometimes the “can’t reset Face ID” issue is just iOS being glitchy rather than a permanent block.

Common quick fixes that users report working:

  • Restart / force restart your iPhone :
    • Normal restart: power off, wait a few seconds, power back on.
* Force restart (varies by model; for recent phones: quick press Volume Up, quick press Volume Down, then hold Power until the Apple logo).
  • Reset all settings :
    • Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.
* This doesn’t erase your data, but it does reset Wi‑Fi, layout, and system settings.
  • Then try Settings → Face ID & Passcode → Reset Face ID again.

These steps help if the Face ID controls are bugged but not intentionally blocked by security features.

4. When it’s a hardware or camera issue

If your iPhone detects a hardware problem with the TrueDepth camera system, you may not be able to set up or reset Face ID at all.

Signs it may be hardware:

  • Messages like “Face ID is not available” or “Try setting up Face ID later”.
  • The camera area is damaged, got wet, or the phone has had a heavy drop.
  • Even after restarts and updates, the Set up Face ID flow fails repeatedly.

Things to try before assuming it’s broken:

  • Remove any thick case, camera cover, or screen protector around the notch.
  • Clean the front camera area with a soft, dry cloth.
  • Make sure your face isn’t blocked (mask, scarf, some sunglasses, etc.).

If it still doesn’t work, Apple’s own guidance is to contact support or visit an authorized service provider.

If your phone is still under warranty or AppleCare, repairs for Face ID hardware failures are sometimes covered.
