When Apple first introduced Touch ID back in 2013 with the iPhone 5S, it felt revolutionary. Suddenly, you could unlock your phone or confirm a payment with just a fingerprint—no need to enter a passcode every time. It was fast, secure, and reliable. For many iPhone users, Touch ID became second nature.
But things changed in 2017 with the release of the iPhone X. Apple removed the fingerprint sensor and introduced a new system called Face ID, which relied on advanced facial recognition. From that moment on, every flagship iPhone abandoned Touch ID in favor of Face ID.
Years later, many people are still wondering: Why hasn’t Apple brought back Touch ID alongside Face ID? Wouldn’t having both options be the best of both worlds? To answer this question, we need to explore Apple’s design philosophy, the security differences between the two systems, and whether we’ll ever see Touch ID make a comeback on future iPhones.
1. The Birth of Touch ID in 2013
When Apple unveiled the iPhone 5S, it wasn’t just another iPhone upgrade. It introduced Touch ID, a fingerprint recognition system built directly into the home button. At that time, competitors were still relying on basic PIN codes or pattern locks.
Touch ID was a leap forward because:
- It allowed instant phone unlocking without typing.
- It made App Store purchases and Apple Pay payments seamless.
- It offered security without inconvenience—your fingerprint became the key.
For years, Touch ID felt like the gold standard for smartphone security. It was fast, intuitive, and reliable in almost all conditions.
2. The Shift to Face ID in 2017
Fast forward to 2017: Apple introduced the iPhone X and decided to remove the home button entirely. This design change forced Apple to think differently about authentication. Instead of moving the fingerprint scanner to the back of the phone like some Android devices, Apple introduced Face ID.
Face ID used the TrueDepth camera system, which projected thousands of tiny infrared dots to create a 3D map of your face. With one glance, your iPhone could now recognize you—whether you were wearing glasses, had grown a beard, or even changed your hairstyle.
This was a bold move. Apple was signaling that Face ID wasn’t just a replacement; it was the future.
3. Apple’s Design Philosophy: One Integrated System
To understand why Apple hasn’t brought Touch ID back, you need to understand their philosophy. Unlike Android manufacturers who often provide multiple ways to unlock a phone, Apple tends to focus on one unified system and perfect it.
Apple values:
- Consistency: They want all iPhones to feel the same.
- Simplicity: Fewer options mean fewer complications for users.
- Integration: Features are only launched if they feel native to iOS.
In Apple’s view, Face ID was designed to do everything Touch ID could—but better and more seamlessly.
4. How Face ID Works (and Why It’s Different)
Unlike standard face recognition on Android phones (which often used just the front camera), Face ID goes much deeper:
- Infrared Camera: Detects your face even in the dark.
- Dot Projector: Projects over 30,000 tiny dots onto your face to map depth and contours.
- Flood Illuminator: Helps capture your face in low light.
- Neural Networks: The A-series chip processes facial data instantly and securely.
This means Face ID isn’t just looking at your face—it’s measuring its shape, size, and depth. That’s why it can adapt if you grow a beard, wear sunglasses, or change your hairstyle.
5. Security Comparison: Face ID vs. Touch ID
Apple has always emphasized security. Here’s how the two systems compare:
| Feature | Touch ID (Fingerprint) | Face ID (Facial Recognition) |
|---|---|---|
| False Acceptance Rate | 1 in 50,000 | 1 in 1,000,000 |
| Works in the dark? | Yes | Yes |
| Works with accessories? | Gloves may block sensor | Adapts to glasses, hats, beards |
| Speed | Fast | Fast (improves over time) |
As the table shows, Face ID is statistically 20 times more secure than Touch ID. For Apple, this was a strong reason to stick with Face ID as the default method.
6. Real-Life Convenience: When Face ID Struggles
So far, Face ID sounds unbeatable. But let’s be honest—it’s not always perfect. There are real-life situations where Touch ID feels more convenient:
- Phone on desk: You need to lift the phone or adjust your head angle.
- Masks during the pandemic: Initially, Face ID struggled until Apple updated it to recognize masked faces.
- Bright sunlight or angles: Sometimes Face ID doesn’t register if the angle isn’t right.
In these cases, a fingerprint scanner would have been faster. That’s why many users still wish Apple offered both.
7. Why Apple Didn’t Launch In-Screen Touch ID
Some Android phones feature under-display fingerprint scanners, so why didn’t Apple follow suit?
According to multiple reports (including Bloomberg), Apple tested in-screen Touch ID around 2019. But Apple is famous for holding back technology unless it meets their strict standards. If it wasn’t:
- Fast enough,
- Reliable enough,
- Seamlessly integrated with iOS,
…it simply wouldn’t ship. Apple likely decided that Face ID was already good enough and that adding in-screen Touch ID would compromise their design philosophy.
8. The Devices That Still Use Touch ID
Interestingly, Apple hasn’t completely abandoned Touch ID. It still exists in several devices:
- iPad Air (2020 and newer) – Touch ID integrated into the power button.
- iPad Mini (2021 and newer) – Same power button integration.
- iPhone SE (2022) – Still features the classic Touch ID home button.
This shows that Apple still values Touch ID, especially in budget or mid-range devices where Face ID might not be practical.
9. Will Touch ID Return to the iPhone?
The big question: Will Apple ever bring Touch ID back to flagship iPhones?
- Possibility 1 – In-Screen Touch ID: Rumors suggest Apple may revisit this in the future, but only if performance meets their standards.
- Possibility 2 – Side Button Integration: Like on the iPad Air, Apple could integrate Touch ID into the iPhone’s power button.
- Possibility 3 – Stick with Face ID Only: Given Apple’s track record, this might remain the most likely outcome.
In short, unless Apple can make Touch ID as seamless and secure as Face ID, it may never return to flagship iPhones.
10. Lessons from Android: Flexibility vs. Perfection
Android manufacturers often give users multiple choices—face unlock, in-screen fingerprint, and sometimes even rear-mounted sensors. This flexibility appeals to users who like having options.
Apple, on the other hand, prioritizes perfection over flexibility. Their approach is:
- If one system works well enough, there’s no need to offer a second.
- Too many options might confuse users or dilute the experience.
This contrast explains why Android leads in flexibility, but Apple maintains tighter control over consistency.
11. FAQs on Touch ID and Face ID
Q1: Is Face ID safer than Touch ID?
Yes. Face ID has a 1 in 1,000,000 chance of being spoofed, compared to 1 in 50,000 for Touch ID.
Q2: Can Face ID work with masks?
Initially, Face ID struggled during the COVID-19 pandemic, but Apple updated the system to recognize partially visible faces.
Q3: Why doesn’t Apple just give both options?
Apple prefers a unified system. Supporting both would mean extra hardware, more cost, and design compromises.
Q4: Will iPhone SE always have Touch ID?
Possibly. The iPhone SE targets budget-conscious buyers and those who prefer the classic design.
Q5: Could we see Touch ID return in the iPhone 17 or beyond?
It’s possible, but only if Apple finds a flawless way to implement it—whether under the screen or in the power button.
12. Final Thoughts
Touch ID was an incredible innovation that changed the way we unlocked our iPhones. But Apple believes Face ID is the future—more secure, more advanced, and more integrated with the iPhone’s design.
Still, many users miss the convenience of a fingerprint sensor, especially in tricky situations. Android continues to lead in offering both, while Apple focuses on refining a single experience.
Will Touch ID return one day? Perhaps. But for now, Apple’s message is clear: Face ID is here to stay.
