- Which SDK this is regarding: auth0-lock
- SDK Version: 11

Hi.  
I want to change error message in login view.  
For example, If there is email account existed and user try sign-up using same email, we want to show “You already registered!” as an error message.  
Can I achieve it by using auth0-lock?

Hi @higuzeroggw ,

Thank you for posting this topic on the Auth0 Community!

I understand you want to customize the signup error message for already existing users in the Classic Login Experience (Lock Widget). [This](https://auth0.com/docs/customize/customize-lock-error-messages) article explains how to customize the error message by providing `languageDictionary` options, `"user_exists"` key.

Hope this helps!
