How to add member password modification function? How to write code

Question

I have set up a system where the front-end user does not have the function to change the password after logging in. I want to add a function to change the password in the user center. How do I write it? Can any great person teach me this? I have been studying it for a long time. I am a novice.

Answer 1

I just want to add the function of modifying the code in the lower left corner of the user center. Can any hero teach me how to do it?

Answer 2

How do you answer this? I don't know what system you have. I don’t know which framework it is. The question is too general
