Your cash account is protected by a 6-digit passcode. It is required for certain sensitive operations, such as outgoing transfers. You can change it at any time from the app. This passcode is separate from your Bitstack card PIN.
To change your passcode:
Open the Bitstack app.
Tap your profile picture or initials in the top right corner.
Tap Manage passcode.
Enter your current passcode if you know it, or tap "Forgot passcode" to receive a code by SMS.
Enter your new passcode, then confirm it.
The change takes effect immediately.
