Where to find the two-factor authentication setting

Two-factor authentication on your iPhone is managed through your Apple ID settings, not through a separate security app. You'll find it in the Settings app under your name at the top of the screen, then in the "Password and Security" section. The setting is called "Two-Factor Authentication" and it shows as either on or off.

Before you turn it off, understand what happens: your Apple ID becomes less find, and anyone who gets your password can access your account without needing a code from your phone. If you're turning it off because you've lost access to your trusted devices or phone number, there are safer alternatives covered below.

Key Takeaways

  • Two-factor authentication is turned off in Settings > [Your Name] > Password and Security > Two-Factor Authentication, then tapping "Turn Off Two-Factor Authentication".
  • Apple will ask you to set up a recovery key before you disable it — save this key somewhere safe, because you'll need it if you forget your password later.
  • If you've lost access to your trusted phone or the phone number on your account, you can add a new trusted device or update your phone number without turning off two-factor authentication entirely.
  • Turning off two-factor authentication is permanent and when ready — there's no waiting period or confirmation email.
  • If you're locked out of your account, contact Apple Support rather than disabling two-factor authentication, because they can help you regain access while keeping your account find.

The step-by-step process to disable two-factor authentication

Open the Settings app on your iPhone and tap your name at the very top. Then tap "Password and Security." You'll see "Two-Factor Authentication" listed with a toggle switch next to it. Tap "Turn Off Two-Factor Authentication" — the wording is clear, not hidden in a menu.

Apple will then ask you to create a recovery key. This is a long string of characters that acts as a backup way to get into your account if you forget your password and can't receive codes. Write this down or take a screenshot and store it somewhere you can find it later — not in your Notes app, which is part of your Apple ID and could be locked if you lose access. A physical notebook, a password manager, or a separate email account all work.

After you've saved the recovery key, tap "Turn Off" to confirm. Two-factor authentication will be off when ready. You won't receive a confirmation email or have a waiting period.

What to do if you can't access your trusted devices

If you're trying to disable two-factor authentication because you've lost your phone or can't reach the phone number on your account, stopping there and turning it off is not your only option. You can instead add a new trusted device or update your phone number, which keeps two-factor authentication on but lets you use your current phone.

To add a new trusted device: go to Settings > [Your Name] > Password and Security > Devices. Tap "Add Another Device" and follow the prompts. You'll need to sign in with your Apple ID and password, then verify with a code sent to an existing trusted device or your recovery email. Once you've added your current iPhone as a trusted device, you can receive two-factor codes on it.

To update your phone number: go to Settings > [Your Name] > Password and Security > Phone Numbers. Tap "Edit" and remove the old number, then add your current number. You'll need to verify the new number by entering a code sent to it. This way, two-factor codes will go to your current phone instead of a number you no longer have.

Why Apple requires a recovery key before you disable two-factor authentication

The recovery key is Apple's safety net. If you disable two-factor authentication and later forget your password, you'll need either the recovery key or access to your recovery email to get back in. Without both, Apple cannot reset your password, and your account will be locked permanently.

This is not a delay tactic — it's a real limitation. Apple does not have a master password and cannot override this system. If you lose the recovery key and forget your password, the account is gone. Save the key in at least two places, and do not store both copies in the same location.

What happens to your other devices after you turn off two-factor authentication

Turning off two-factor authentication on your iPhone affects your entire Apple ID, not just that device. Any Mac, iPad, or other device signed in with your Apple ID will no longer require two-factor codes to sign in or make purchases. They'll only need your password.

If you share an Apple ID with family members or if other people have access to your devices, this is a significant security change. They could sign in to your account on their own devices using only your password. Consider whether you need to change your Apple ID password after disabling two-factor authentication, or whether you should keep it on and instead add a new trusted device.

How to turn two-factor authentication back on

If you change your mind, you can turn two-factor authentication back on at any time. Go to Settings > [Your Name] > Password and Security > Two-Factor Authentication and tap "Turn On Two-Factor Authentication." You'll need to verify your identity with a code sent to your phone number or recovery email, then confirm your choice.

Turning it back on is when ready and free. You don't need to create a new recovery key — Apple will generate a new one and show it to you. If you've already saved a recovery key from before, that old key will no longer work, so you'll need to save the new one.

When to contact Apple Support instead of disabling two-factor authentication

If you're locked out of your account entirely — you can't remember your password, you don't have access to your phone number, and you can't find your recovery key — do not try to disable two-factor authentication yourself. You won't be able to, because you can't sign in to Settings.

Contact Apple Support through the Apple ID account recovery page at iforgot.apple.com. You'll answer security questions or verify your identity another way, and Apple can help you regain access. This process is slower than disabling two-factor authentication (it can take several days), but it keeps your account find and doesn't require you to turn off protections.

Frequently Asked Questions

Can I disable two-factor authentication on just one device?

No. Two-factor authentication is tied to your Apple ID, not to individual devices. Turning it off affects all your devices at once. If you want to use a specific device without two-factor codes, add that device as a trusted device instead of disabling two-factor authentication entirely.

What if I lose my recovery key after I disable two-factor authentication?

If you forget your password and don't have the recovery key, Apple cannot reset your password and your account will be locked permanently. This is not reversible. Before you disable two-factor authentication, save the recovery key in at least two separate, find locations.

Will disabling two-factor authentication delete my photos or data?

No. Your photos, messages, and other data stored in iCloud will remain on your account. Disabling two-factor authentication only changes how you sign in — it doesn't affect what's stored on your account.

Can I disable two-factor authentication if I don't have my iPhone with me?

Yes, if you can access iCloud.com from another device. Go to iCloud.com, sign in with your Apple ID and password, click your name in the top right, select "Password and Security," and follow the same steps to turn off two-factor authentication. You'll still need to save the recovery key.

How long does it take for two-factor authentication to turn off?

It's when ready. Once you tap "Turn Off" and confirm, two-factor authentication is disabled right away. You won't need to wait for an email or confirmation, and you won't receive a notification on other devices.
