# Had wallet (The user updates app)

* Condition: The app already has a wallet (The user updates the app).
* When the user has installed the app and updated the app to the version with the security function, please follow the steps below to create a passcode. 

**Step 1**

* Open the app --> The "Create Passcode" screen will be displayed.                                                                                                          ![](/files/nL1MMsEivjbVCc49D09P)

**Step 2**

* Enter 6 digits to create a passcode.

**Step 3**

* Re-enter to confirm the passcode.                                                                                                                                                                            ![](/files/wy9lenAtNCgUs57ZI3gV)

**Step 4**

* If re-enter correctly --> Create passcode successfully and redirect to the Home screen.                                                                                                          ![](/files/JpXEpvSX3H4fla1NZQ32)
* If re-enter incorrectly --> Return to Step 3 to re-create passcode.

***Note:***

* Users can tap on "SKIP" if they don't want to use the security lock. 
* If the app already has a wallet and passcode but the user deletes all wallets, they must create a new passcode when accessing the app to create or import a wallet.
