Auto populate a user custom field from another user custom field

I have a WP theme with its own custom fields including one for Phone Number. I also installed the Digits Plugin which allows users to sign up/login with their phone number and OTP, which has its own phone number custom field.

What I want to do is to use the phone number they use to sign up/login to also be the phone number used within the theme and also within Woocommerce if possible.

Any help would be appreciated
