When I turn on my iPhone SE 2020, it does not ask for my Touch ID. Why not?

As explained above, if the phone is powered off completely, when you turn it on, it will ask for your Passcode to open it. As long as the phone is powered on, it will use Touch ID after you've signed in with your passcode. You will have to enter your passcode after an iOS update, a forced restart and when it is powered on after being shut down. When you turn it on after being powered off, it will not ask for the passcode AND touch id. It will only ask for the passcode once.

The bottom line is your phone is operating as designed.

• I set up Touch ID (thumb) and passcode for iPhone SE 2nd Gen security.

In Accessibility, Home Button, Rest Finger to Open is set to on.

• iPhone unlock is turned on.

• Itunes and App Store are turned on.

• (Much of iCloud is turned off on this iPhone for now.)

When I open my iPhone SE 2020, it only asks for my passcode. It does not ask me for my Touch ID on the Home button.

Why not? Are other settings required?

Open? do you mean that it was turned off and you are turning it on?

Should be this case, it's normal, as per this paragraph:

Your device will require your passcode when you do the following:

• Turn on or restart your device
• Press the Home button or swipe up to unlock your device (you can change this)
• Update your software
• Erase your device
• View or change passcode settings
• Install iOS or iPadOS Configuration profiles

To summarize...

You have an iPhone that is off. You restart the iPhone. The iPhone prompts for the passcode or password, amd will not accept the Touch ID or Face ID. The iPhone also reports a message indicating that the passcode or password is required to enable Touch ID or Face ID after a restart. Once the passcode or password is entered once, the iPhone then accepts Touch ID or Face ID.

This is normal and expected.

Touch ID and Face ID are not what protects your data. It is your passcode or password that protects your data. The better your passcode or password, the better protected your data.

And again, Touch ID and Face ID are a shortcut intended to allow you to use a better passcode or password without having to re-enter it all the time; for secondary protection and ease-of-use, not primary protection.

Verify that your sibling has seen the Apple logo when first turning on the iPhone, and is not misinterpreting the display sleep function with an iPhone restart. Because if there’s a problem here, it is with your sibling’s device and not yours. But I’d expect this is an iPhone that was not restarted, but rather reawakened.

Or your sibling is gaslighting you.

It's really not misleading. But I suppose if you've never owned an iPhone with either Touch ID or Face ID, you could be confused. Think about this. You're asleep. Your phone is powered off. Someone turns your phone on, and uses your finger to gain access to your phone when they turn it on. They then go to your Apple Wallet and buy something using your credit card. Your phone would lack much security in such a scenario. One thing you'll learn quickly about Apple is that they take your personal security of your device and your data on your device VERY seriously and they make it very difficult for anyone else to gain access to your device other than you.

When you first reboot your iPhone or iPad, you will be prompted for your passcode.

Touch ID and Face ID are a means to avoid entering your passcode or password as often.

Touch ID and Face ID are not a replacement for your passcode or password.

Touch ID and Face ID make it (much) easier to use a longer passcode, or a more robust password.

But your passcode or password will always be required for certain actions.
