WordPress doesn’t have an default option to save modified date. So we have save modified date when user updating their profile.
You can save the modified date by adding the following code in your theme’s functions.php file.

You can get this date by using get_user_meta() function. for example see below code.

$modified_date = get_user_meta( $user_id, 'modified_date', true );
