A PIN code is your wallet password. When you create a wallet, after backing up your mnemonic phrase, the wallet will prompt you to set a six-digit password, which is your PIN code. After setting up the PIN code, you will need to enter it each time you open the wallet. You can also enable biometric authentication (fingerprint, facial recognition, etc.) in the wallet settings of the app to replace entering the PIN code.
You can change your PIN code by opening the Bitpie wallet:
- Click on the bottom right "Wallet Settings"
- Select "Unlock/Payment Password Modification"
- Enter your original PIN code to make the change.
