You probably secure your iPhone with Touch ID or a passcode. If you have an Apple Watch, you can secure that against unauthorized access as well. Additionally, you need to have a passcode enabled on your watch to be able to use Apple Pay.

您可能使用Touch ID或密码来保护iPhone。 如果您有Apple Watch，也可以防止未经授权的访问。 此外，您需要在手表上启用密码，才能使用Apple Pay 。

您可能会想，“但是，我不想每次要使用手表时都在那个小屏幕上输入密码。” 幸运的是，事实并非如此。 在某些情况下，您仅需要在Apple Watch上输入密码，例如：

• You remove your watch from your wrist and put it back on您将手表从手腕上取下并重新戴上
