Auth0’s Log In / Sign Up tabs are easily missed by customers. To make matters worse, if you’re under the “Sign Up” tab, and the customer attempts to login, the error message simply says “We’re Sorry, Something went wrong when attempting to sign up”. Is it possible to change that to say “There’s already an account using this email address” - or is that considered a security feature to not give that information away?

Hi @cam,

Welcome back!

This is an OWASP recommendation if I remember correctly, to protect against email enumeration.

You can customize this error though.

If you are using classic UL:

> **[Customize Lock Error Messages](https://auth0.com/docs/customize/customize-lock-error-messages?_ga=2.112038851.673017969.1605195140-1261373470.1602622721)**
>
> Customizing error messages with Lock v11

If you are using New UL:
