# Lock a notebook

Locking a notebook adds an extra layer of privacy to your notes. This feature is available for **Premium** users and allows you to protect sensitive information with a password or passcode.

> **Note:** UpNote does not support locking individual notes.\
> To protect a specific note, place it inside a locked notebook.

### 🖥 On Desktop (Windows & macOS)

#### **Recommended: Sign In Before Using Lock**

We recommend signing in to your UpNote account before enabling lock.\
This ensures that if you forget your lock password, you can sign out and reset it safely.

#### **Enter and Manage Your Lock Password**

When accessing a locked notebook, you’ll be asked to enter your lock password.

* By default, this is your **account login password**.
* You can change it via **Settings → General → Lock → Change lock password**.

#### **Navigate Between Locked Notebooks**

By default, UpNote requires you to enter your lock password every time you access a locked notebook.

If you prefer to keep the unlocked session active:

1. Go to **Settings → General → Require re-enter password**
2. Or adjust this setting directly from the lock screen.

For quicker unlocking, enable:

* **Touch ID / Face ID**

#### **If You Forget Your Passcode**

If you forget your passcode lock:

1. Sign out of UpNote.
