The Yuh Key is a passcode of at least 6 digits that gives you access to your Yuh account.
You set up this passcode during the account opening process. The Yuh Key is not your debit card PIN code.
You are prompted to enter the Yuh Key:
to log into your Yuh account for the first time (or on a new device)
to make payments through the app
for the initial activation of your debit card
to display your debit card details
when changing sensitive personal information in the app (such as choosing a new debit card PIN number)
After you have linked your device to your account with your Yuh Key, you can simply log into the app by using your preferred unlock method for your device (biometric, pattern, passcode, or other).
