What needs to be fixed

The file \components\com_users\models\forms\registration.xml is buggy and not referencing the right Label and Description of translation.

	<field
		name="password1" 
		type="password"
		label="COM_USERS_PROFILE_PASSWORD1_LABEL"
		description="COM_USERS_DESIRED_PASSWORD"
		autocomplete="off"
		class="validate-password"
		field="password1"
		filter="raw"
		size="30"
		validate="password"
		required="true"
	/>

	<field
		name="password2"
		type="password"
		label="COM_USERS_PROFILE_PASSWORD2_LABEL"
		description="COM_USERS_PROFILE_PASSWORD2_DESC"
		autocomplete="off"
		class="validate-password"
		field="password1"
		filter="raw"
		message="COM_USERS_PROFILE_PASSWORD1_MESSAGE"
		size="30"
		validate="equals"
		required="true"/>

Why this should be fixed

It should be fixed because not mapping the right things (it is like a copy and paste mistake)

How would you fix it

I would replace
label="COM_USERS_PROFILE_PASSWORD1_LABEL"
by
label="COM_USERS_REGISTER_PASSWORD1_LABEL"

and replace
label="COM_USERS_PROFILE_PASSWORD2_LABEL"
by
label="COM_USERS_REGISTER_PASSWORD2_LABEL"

It seems to have similare confusion in the rest of the form

Side Effects expected

It is confusing to amend the translation fileld (xx_XX.com_users.ini) and tune the registration form to make it more explicit.
Some users don't have the reflex to pass the mouse on the name field to display the modal and get stuck to register...it seems to be obvious but some clients don't know how to...it is the hard life UX vs client exeperience !
