Unable to lock notes

I got nervous resetting my password before removing the lock on all my notes. I removed the lock on every note I had it set for (even though I could unlock my notes without a problem), and reset my password. Now I am able to lock and unlock my notes without any issues. Thank you so much for your help!! :)

Hi icepenguin19,

Thank you for using the Apple Support Communities! I understand you are having trouble locking notes in the Notes app. I'd like to help.

Thanks for letting me know you are able to unlock previously locked notes without issue, and that your notes are synced to your iCloud account. It's also helpful to know the error you are running into when you do attempt to lock a new note. Prior to troubleshooting, I would recommend trying to restart your iPhone: Restart your iPhone - Apple Support, and make sure it is on the latest iOS version available: Update your iPhone, iPad, or iPod touch - Apple Support. Since your notes are connected to iCloud, first try toggling iCloud notes off and back on to re-sync the notes. Does that help?

If the issue remains, what happens when you attempt to change your Notes password? If you can't change it because it says the old password is incorrect, can you try resetting it instead? Lock notes on your iPhone, iPad, iPod touch, and Mac - Apple Support.

Keep me posted. Regards.

I have the same issue as icepenguin19. Notes (iOS 13.3) are all in iCloud on my iPhone 8, I can unlock an already-locked note with touchID or password just fine, but trying to lock a new note on the iPhone always results in "That's not the correct password. Please try again."

I have restarted the phone, and also toggled off the Notes switch under Settings > iCloud (deleting Notes from iPhone), then on again. Same issue.

Then I go to my MacBook Pro running High Sierra. (10.13.6) and with the same iCloud-based Notes. Same issue—unlock is fine, trying to lock a note results in a rejection of the password.

I guess I am down to the point of changing my Notes password. This scares me a little, as I don't want to get locked out. An application acting buggy around passwords is nothing to take lightly, especially with the importance of some of the Notes I have.

Icepenguin19, you reset your password, rather than changing it? I am curious if you tried changing the password first. I plan to change my password after removing the lock from all notes (need to do so from 32 notes)—nice idea for playing it safe, thanks.

Reading the help, resetting your password potentially leaves behind the original password in some way, so I plan to change my password instead.

Do not like this buggy behavior in Notes!

Same issue as above however I am not set up to sync with I Cloud for Notes

So did anything helped for you. I have been having same issue with my iPhone XS Max too. Nothing has worked for me.
