Your sign-in codes, kept on your own device. Welcome to HTT Auth. This is the app that keeps your six-digit sign-in codes for every HTT account. You will set it up.

## Step by step

### 1. Open the app

Open HTT Auth in your browser. The first time you open it on a device, it asks you to choose a PIN.

*Step 1: Open the app*

### 2. Why a PIN

The PIN unlocks your codes on this device. It is never sent anywhere, and never stored — so choose something you will still remember in six months.

*Step 2: Why a PIN*

### 3. Choose a PIN

Type your PIN — at least six digits — then type it again to confirm, and press Continue.

*Step 3: Choose a PIN*

### 4. Home screen

This is your home screen. Your codes will appear here, each one refreshing every thirty seconds.

### 5. The buttons

Along the top: Add account, to add a code. Backup, to save an encrypted copy. Recovery codes, for when you cannot reach this app. And Settings.

*Step 5: The buttons*

### 6. Lock

When you step away, press Lock. Your codes are encrypted, and nobody can see them without your PIN.

*Step 6: Lock*

### 7. Unlock

To open the app again, type your PIN and press Unlock. Remember — this is the PIN you just chose, not your HTT password.
