I would like to add a page where I can just change my password on my page after registering or logging in.
Is it possible to achieve this if I edit the liquid?
Or is it possible to do this by using an app like cutomer fields?
Sorry for the late reply, I just discovered this post!
The Customer Fields app does not allow a customer's password to be changed using the app. Please reference Shopify's instructions for resetting a customer's password.
