Your Passcode Is Required to Enable Face ID? Fix
If your iPhone says “Your passcode is required to enable Face ID,” it means the device needs you to enter your passcode once before Face ID can be set up or used again. This is a security measure, not an error—enter your passcode and Face ID will work normally.
Why This Message Appears
Face ID is designed to protect your data, so Apple requires your passcode in several situations:
- After a restart: The iPhone must be unlocked with the passcode before Face ID can start recognizing you.
- After 48 hours without unlocking: If you haven’t entered your passcode in two days, Face ID is disabled until you do.
- After a failed Face ID attempt: If someone (or something) tries to unlock with Face ID and fails five times, the device locks and asks for the passcode.
- When setting up Face ID: If you’re adding a new face or resetting Face ID, the phone asks for your passcode to confirm it’s you.
- After a software update: Some iOS updates require a passcode entry before Face ID re-enables.
This is a deliberate security feature. It prevents someone else from using your face to unlock your phone if they have a photo or a 3D mask, and it ensures that only you can re-enable biometric authentication.
How to Fix It
- Wake your iPhone by pressing the side button or tapping the screen.
- When the “Enter Passcode” screen appears, type your six-digit passcode (or whatever you set).
- After unlocking, Face ID will work again immediately. You can test it by locking the phone and waking it with a glance.
If you don’t see the passcode screen, try pressing the side button twice or swiping up from the bottom. If the message persists, restart your iPhone and try again.
What If You Forgot Your Passcode?
If you don’t remember the passcode, you cannot bypass it. The only way to regain access is to erase the iPhone and restore from a backup. Here’s what to do:
- Connect the iPhone to a computer and open Finder (macOS) or iTunes (Windows).
- Put the iPhone into recovery mode (the exact button combination depends on the model, but for most modern iPhones, press and hold the side button and a volume button until the recovery mode screen appears).
- Choose “Restore” in Finder/iTunes. This wipes the device and installs the latest iOS.
- After restoring, you can set it up as new or restore from a backup you made before.
This is a drastic step, so only do it if you’re certain you can’t recall the passcode. If you have an iCloud backup, you can also erase the phone remotely from iCloud.com.
Why Face ID Disables After Failed Attempts
Face ID uses a neural network to compare your face with the stored mathematical representation. If it fails five times in a row, the phone assumes someone else is trying to unlock it, so it locks the Face ID feature and requires the passcode. This is similar to how entering the wrong passcode multiple times locks the phone for increasing durations.
You can reduce accidental failures by making sure the camera is not blocked, you’re not wearing a mask that covers your face (unless you’ve set up “Face ID with a Mask”), and you’re looking directly at the screen.
Face ID vs. Passcode: Which Is More Secure?
Face ID is convenient, but the passcode is the ultimate fallback. Apple states that Face ID has a 1 in 1,000,000 chance of being fooled by a random person’s face, while a six-digit passcode has a 1 in 1,000,000 chance of being guessed. However, the passcode is the only thing that can unlock your phone if Face ID fails, so it’s critical to choose a strong one.
For maximum security, use a longer alphanumeric passcode (mix of letters and numbers) rather than a simple six-digit number. You can change it in Settings > Face ID & Passcode > Change Passcode.
Frequently Asked Questions
Why does my iPhone ask for my passcode every day?
It might be because you haven’t entered your passcode in the last 48 hours. Apple’s security policy requires a passcode entry at least once every two days. If you use Face ID constantly, you might not realize that you haven’t typed your passcode recently. Just enter it when prompted, and the timer resets.
Can I disable the passcode requirement for Face ID?
No. The passcode is required for security. You can’t turn off the requirement entirely, but you can change the frequency by entering your passcode more often. The 48-hour rule is built into iOS and cannot be changed.
Does Face ID work with a mask?
On iPhones with Face ID, you can set up “Face ID with a Mask” (iOS 15.4 and later) that works with certain masks. However, if you’re wearing a mask and haven’t set this up, Face ID will fail and eventually ask for your passcode. You can also use an Apple Watch to unlock your iPhone when wearing a mask, if you have that feature enabled.
What if Face ID is not working after I enter my passcode?
If the message disappears but Face ID still fails, check that the TrueDepth camera is not blocked by dirt or a screen protector. Go to Settings > Face ID & Passcode and make sure Face ID is enabled for the features you want. If it still doesn’t work, you may need to reset Face ID and set it up again.
Is it safe to share my passcode with someone?
No. Your passcode is the master key to your iPhone. Anyone with your passcode can change your Face ID, access your passwords (if you use iCloud Keychain), and see all your data. Never share it, and be cautious when entering it in public.
Why does my iPhone ask for my passcode after a software update?
iOS updates often reset security settings or require a fresh authentication to ensure the device wasn’t compromised. After an update, the phone may ask for your passcode once to re-enable Face ID. This is normal and only happens occasionally.
