How to Lock a Note with a Password or Touch ID in iOS

With the release of the latest version of iOS, you can now protect your notes in the Notes app using either a password or Touch ID. For me, this was really great news because I use the Notes app a lot on my iPhone, but hate the fact that I have to use a different app like Evernote when creating sensitive notes that I want to protect.
Overall, the feature works fairly well, though there are some strange quirks that I hope get ironed out over the next few iOS releases. In this article, I’m going to walk you through the steps for creating a locked note in iOS and how to use them properly.
How Locked Notes Works in iOS
Before we get into the actual process, it’s important to go over how locked notes really work in iOS. Firstly, all notes will be locked using a single password and that is a requirement. If you want to create locked notes, you have to supply a password.
This password will be used for all your locked notes. You can’t easily create different passwords for different notes. It’s possible to have different passwords on different notes, but it’s not how the feature is supposed to work and I’ll explain below how this situation can occur.
Secondly, notes can also be locked using Touch ID. Any fingerprint that can unlock your phone will be able to unlock your notes if you enable Touch ID for locked notes. If you use Touch ID, you don’t have to enter the password, though you can if you like. It’s pretty much the same way you can use Touch ID on your lock screen or enter your passcode.
Lastly, there are a few strange quirks. For example, even if you lock a note, the title of the note is visible in the Notes app. So when creating a secure note, make sure the first line is something that you don’t mind others being able to see.
The other odd quirk is that you can delete a locked note without any authentication. So if someone get access to your phone, even though they can’t view the note, they can delete it! In my opinion, it should require the same authentication for deleting locked notes as it does for viewing.
