A Guide to TouchID and Passcode for iOS

Last modified

In this guide, I'll be teaching you how to use Touch ID on your iPhone, if you have never used it.

Why Is This Guide Necessary?

It may seem like people who are reading this guide already are familiar with TOUCH ID and passcode settings, and it may seem like this guide isn't as necessary, since there is a "Getting Started with your First iOS device" link, but I want to help out people who are just starting with an iPhone.


As far as I've heard, Touch ID is only available for the devices below.

• Supported TOUCH ID Devices:

iPhone 5S

iPhone 6/6 Plus

iPhone 6S/6S Plus

iPhone SE

iPhone 7/7 Plus

iPhone 8/8 Plus

Some iPad Pro models also support Touch ID, and some models after the iPad Air have a Touch ID integrated into them.

• Not Supported TOUCH ID Devices:

iPhone X (Supports Face ID, not Touch ID)

iPhone 5/5C

Anything below iPhone 5S, as far as I know, do not have Touch ID. The iPhone X is also included because iPhone X has a new feature called Face ID.

In this guide, I will be using the Touch ID layout of my iPhone 6S 64GB.

What Is Touch ID?

Touch ID, is a fingerprint recognition system that helps secure your phone. It works in line with your passcode, so you can't have TOUCH ID as an option unless you have set a desired passcode.

To use Touch ID, you place your finger on the home button, and it unlocks your phone.

How do I Get Touch ID Up and Running?

As said above, Touch ID requires a passcode before you can use it.

To set a passcode, go to

Settings>Touch ID and Passcode.

If you launch Touch ID and Passcode with a passcode already set, you will be prompted to enter it to continue. If you do not have a passcode set, it will just open without any prompts.

We are just going to assume you don't have a passcode set, for people who don't.

Most of the other buttons will be dimmed, except Turn Passcode On. Select Turn Passcode on, and type in your 4-digit passcode.

If you do not want a 4-digit code, you can select Passcode Options, and change it to 6-digit Numeric Code, or a Custom passcode consisting of letters and numbers, as long as you want.

Type in your desired passcode, and if using custom, press done. If you are using limited digits, it will automatically recognize it.

After this you will be asked to re-enter your passcode. Enter the same passcode you used the first time, and hit Done or it will automatically recognize.

Warning!: Choose a passcode that you can remember, but others can't.

Now that you have your passcode enabled, the bkttons that were previously dimmed will now be available to toggle.

Configuring TOUCH ID

Finally, we've reached where you can configure TOUCH ID.

Under the FINGERPRINTS heading, an Add a Fingerprint button is available. Double-tap this button, and you will be asked to place your finger.

Place the desired finger on the home button, and you will feel your phone vibrate.

Listen to VoiceOver. When it says lift your finger, and your phone vibrates, lift it. Then it will say place your finger, and you do the same thing again.

Do this at least seven times until you get to the Adjust your Grip screen.

Adjust your Grip

Adjusting your grip basically allows you to capture the edges of your finger that Touch ID might of missed.

Keep doing the same thing, placing your finger, lifting it when your phone vibrates, but this time, try to shift your finger a bit to get some edges. This is recommended so TOUCH ID doesn't say "try again" to you when you try to unlock your phone.

Warning: Don't shift too much, or your phone will prompt you to stop moving your finger.

Touch ID will bring up results about your finger when you finish the Adjust your Grip step.

Now that Touch ID is set up, you can do a few things.

Using it with Other Apps

Some apps support the Touch ID feature, like the App Store. If you enable App Store in the Use Touch ID for section, just above the fingerprints heading, you can use TOUCH ID to confirm app store or iTunes Store downloads. Apple Pay, also if enabled, can be used with TOUCH ID as well.


I hope this guide helped everyone who are new to TOUCH ID.

Note that the iPhone X does not support Touch ID -- it only supports Face ID.

Also, some of the iPad models (the Pro models, I think) do support Touch ID.

Just to reiterate the previous post, TouchID was indeed present on the 5S, 6 & 6 Plus, and the rest of the ones you listed. Having once a 6 Plus, that was one of the features I loved about it.

Thank you for this excellent guide. I was at my parents' place last weekend for Father's Day, and had one of my sisters help me set up Touch ID on my iPhone. Somehow though I think it got screwed up, because my phone keeps telling me to try again when unlocking it. But I've enabled the pass code feature too and it works fine. Is it true that Touch ID can also be used on websites? That'd be pretty handy for me, although I'm gonna explore Braille Screen Input as well. But thanks again.

It depends. If you are trying to auto fill fields in Safari, you can use TOUCH ID to access your account passwords, then select one to auto input. But I don't think any sites, as far as I know, have touch ID support.

However, I have seen an app with Touch ID support for login, a game called Godville. That's a different story entirely though.
Getting back on topic, the answer is on the fence, between yes and no.

Thanks. Yes I'm only trying to use Touch ID for my log-in credentials. I just tried deleting what I had and starting over from scratch, and I think it's okay thus far. I'm just very new to the whole Touch ID thing, but eventually I'll get it. I'm one of those who takes awhile to enter log-in credentials, so I think this will be perfect.
