What's the difference between the password and passcode?

Your passcode (a six-digit code chosen by you) is what you use to access the Zumo Trade and GBP (pound sterling) custodial wallets. Your password (which can be any combination of letters, numbers and symbols you choose) is what you use to access the Zumo Infinite non-custodial wallet.

If you have Zumo Trade only, you will have one single six-digit passcode, and use that passcode to log in to the Zumo app.

If you have Zumo Trade and Zumo Infinite, you will have a passcode for Zumo Trade and a password for Zumo Infinite. You will use your passcode to log in to your Zumo app, and your password only for the Zumo Infinite-specific area of the app.
