I have encountered this problem before, and it is quite easy to solve it. Next, I'll tell you how to operate:

Tool: Glory play5

Step 1: Open Alipay and click Settings in the upper right corner. (as shown in the figure below)

Step 2: Enter Settings and click Payment Settings. (as shown in the figure below)

Step 3: Enter the payment settings page, and click Bio-payment. (as shown in the figure below)

Step 4: Find the mobile phone that pays by brushing face, and click Close. (as shown in the figure below)

The above is all the steps to solve the problem of how to close the face payment of mobile Alipay. If it's useful to you, remember to like it for me ~
