Custom error messages for login, signup and request password change using custom UI

I have designed a custom UI for the hosted login page by modifying the custom UI template provided through the dashboard. I know that if you are using lock you can customize the error messages by providing a languageDictionary option. There also seems to be a way of customizing error messages on a hosted password reset page using dict options.

Is it possible to customize the error (and success) messages for login, signup and request password change if you are using a custom UI on a hosted login page?

If we are talking about Hosted Pages, then You can use the same languageDictionary because the Hosted Login Page uses the Lock Widget to allow your users to authenticate by default.

Kind regards,

I am using the hosted login page but I am not using the lock widget. I am using the custom UI template provided from the drop-down on the hosted login page so languageDictionary is not an option

Have you checked this example?

It is possible that this might help.
