How to Lock Private Notes with Face ID on iPhone
The Notes app can do more than hold shopping lists and quick reminders. It can also protect sensitive information, such as passport details, private journal entries, recovery codes, medical notes, or plans you do not want visible when someone else is using your iPhone. With Face ID enabled, opening a protected note usually takes a glance rather than a separate password entry.
Apple’s note-locking feature is useful, though it has a few rules that are easy to miss. A locked note is protected inside the Notes app, while the rest of your iPhone remains available as normal. The steps are similar on recent iOS versions, including iOS 18, but the location of the Notes password setting can differ on older iPhones.
| Situation | Best protection | What to know |
|---|---|---|
| Private text, lists or journal entries | Locked note with Face ID | Works well for individual notes |
| Several personal notes | Notes password plus Face ID | The same Notes password protects locked notes |
| Notes synced to several Apple devices | iCloud Notes with locking enabled | Locked notes need compatible software and account access |
| A note shared with another person | Standard device security | Shared notes cannot normally be locked |
| Passwords or banking details | A dedicated password manager | Notes is convenient, but not designed as a full security vault |
Check Your iPhone Before Locking A Note
Face ID requires an iPhone model with Face ID hardware, such as an iPhone X or a newer Face ID model. Your iPhone also needs a passcode. Face ID is an extra way to unlock a protected note; it does not replace the device passcode, and iOS may ask for that passcode after a restart or after several unsuccessful Face ID attempts.
Update iOS before setting everything up. Open Settings, tap General, then choose Software Update. Apple often changes menu names and locations slightly between releases, so an older iPhone may show Settings > Notes, while a newer version may place the option under Settings > Apps > Notes.
Make sure Face ID itself is working by opening Settings > Face ID & Passcode. Confirm that Face ID is configured and that the iPhone passcode is active. If Face ID is failing generally, locking a note will not fix the underlying issue. Clean the TrueDepth camera area, remove anything covering the top of the screen and test Face ID from a normal distance.
Set Up The Notes Password And Face ID
Open Settings and look for the Notes security option. On many current iPhones, go to Settings > Apps > Notes > Password. On some earlier iOS releases, the path is Settings > Notes > Password. If you use more than one Apple account for Notes, iOS may ask which account you want to configure.
Choose Use Device Passcode if you want locked notes to use your normal iPhone passcode. This is usually the simplest option because there is no second password to remember. You can also create a separate Notes password, then turn on Use Face ID when the option appears. Follow the prompts to create a password hint, taking care not to make the hint obvious to someone who knows you.
A custom Notes password has an important limitation: Apple cannot recover it. Resetting the Notes password lets you protect new notes, but it does not unlock older notes protected by the forgotten password. If the password is lost and Face ID no longer works, the contents of those older notes may be inaccessible.
For Australians using an iPhone across personal and work accounts, check the account shown during setup. An iCloud Notes password and a password for an account such as Microsoft Exchange may not behave in exactly the same way. Work-managed iPhones can also have restrictions set by an employer or government department, which may prevent some security settings from being changed.
Lock An Existing Note In Seconds
Open Notes and select the note containing the private information. Tap the More button, shown as three dots in a circle, then choose Lock. Depending on the iOS version and screen layout, you may see a padlock icon or find Lock after tapping the sharing or More menu.
If this is the first note you have locked, iOS will ask for the Notes password or device passcode and may request permission to use Face ID. Approve that request if you want quick access. The note will then show a padlock symbol in the notes list, and its contents will be hidden when it is locked.
To lock it straight away, tap the open padlock icon at the top of the note. You can also leave the Notes app or press the side button, allowing the app to lock protected content according to your iPhone’s security behaviour. Return to the note and tap it to authenticate with Face ID. If the scan does not work, tap the password option and enter the relevant passcode.
The same process works for a new private entry. Create the note, enter the text, then use the More menu and select Lock. Locking is applied to that particular note, so an ordinary grocery list elsewhere in Notes will remain visible unless you protect it separately.
Understand What A Locked Note Protects
When a note is locked, its main contents are concealed in the Notes list and when the note is opened. The title may still be visible, however. A title such as “Tax file number” or “Private health information” can reveal more than intended, so use a neutral title if the subject itself is sensitive.
Notifications and previews can also expose information if you share a note through another app or copy text elsewhere. Locking a note does not stop someone from seeing content that has already been pasted into Messages, Mail, a web form or a screenshot. It protects the note in Notes; it does not retroactively protect copies stored in other places.
Photos and scans inside a locked note are generally hidden along with the note’s content. Still, check the original item in the Photos app or Files if privacy matters. A scan of an Australian driver licence may exist in Photos even after it has been added to a locked note, and the original file can have its own sharing and backup history.
Locked notes are also different from a password manager. They are handy for a private diary entry, an itinerary, or details for a weekend in Melbourne, Perth or the Gold Coast. They are less suitable for storing a large collection of banking credentials because they do not provide the specialised autofill, breach alerts and structured security features found in a dedicated password manager.
Know The Limits Of Notes Locking
A note that is shared with other people cannot normally be locked. If you collaborate on a note for a household budget, school timetable or barbecue shopping list, locking it would prevent the shared editing experience. To protect private material, create a separate personal note rather than placing it beside shared content.
Some attachments and note features may prevent a note from being locked. Apple has historically excluded certain document types, including PDFs and iWork files such as Pages, Numbers and Keynote documents. Videos and some other rich media can also cause restrictions. If the Lock option is missing, remove or move the unsupported attachment to a separate location, then try again.
A locked note may also behave differently across devices. If you use an iPad or Mac signed in to the same Apple Account, update those devices so they support the current Notes security system. An older Mac running an earlier version of macOS may not display or open a note in the same way as a current iPhone.
The protection also depends on your wider Apple Account security. Turn on two-factor authentication, use a strong device passcode and keep iOS updated. Avoid leaving an unlocked iPhone on a café table in Sydney, Brisbane or Adelaide, even if private Notes are protected. Device access, account access and note access are related, but they are not the same layer of security.
Find And Unlock Protected Notes Safely
Locked notes remain in their original folder. Open Notes and look for the padlock symbol, or use the search function to locate the note by its title. Search may show the title while keeping the body hidden. Tap the note, then authenticate with Face ID, the device passcode or the custom Notes password.
After unlocking one note, other locked notes may remain available for a short period while Notes is open. This makes it easier to work through several private entries, but it also means you should close Notes or lock the iPhone when finished. Press the side button rather than leaving the phone open on a desk at work or on public transport.
To remove protection, open the note, authenticate, tap the More button and choose Remove Lock. The note will return to the normal Notes list. This does not delete the note, change its folder or remove it from iCloud, so check that the information is still appropriate for every device and account where it syncs.
If a note will not unlock with Face ID, tap the password option and use the correct credential. Check whether you are entering the device passcode or a separate Notes password. Restarting the iPhone can require the device passcode before Face ID becomes available again, which is expected behaviour rather than a sign that the note has been erased.
Keep Private Entries Private Over Time
Review the notes you have protected and remove details that no longer need to be stored. Old travel plans, expired verification codes and outdated copies of identity documents can create unnecessary exposure. Delete sensitive notes properly, then check the Recently Deleted folder in Notes and remove them there if they should not remain recoverable.
Use descriptive but discreet titles. “Journal 2025” says less than “Medicare claim dispute”, and “Reference” is less revealing than “Home alarm code”. This small habit matters because note titles and folder names can be visible before Face ID is requested.
If you rely on iCloud, confirm that Notes is enabled under Settings > [your name] > iCloud > Notes. iCloud syncing is convenient when moving from an older iPhone to a new model bought through an Apple Store, Telstra, Optus or another Australian retailer. It also means a locked note may travel to other signed-in devices, so protect those devices with their own passcodes.
Avoid using Notes as the only place for irreplaceable records. A private diary entry can be backed up through iCloud, but a recovery code or financial record may need a more deliberate storage plan. Keep your Apple Account recovery details current, enable two-factor authentication and check which people or devices have access to your account.
Locking a note with Face ID is a practical way to add privacy without installing another app. Set up the Notes password first, protect only the entries that need it, use neutral titles and remember that shared notes and some attachments have restrictions. Those steps make the feature reliable for everyday private information on an iPhone in Australia and elsewhere.
Open Notes now, choose one low-risk personal entry for a test, lock it and confirm that Face ID can unlock it before moving sensitive details into the app.
