How do I change the messaging for user who doesn't exist?

I am using okta-signin-widget for login. How do I change the error message for the cases where the user hasn’t registered on the platform and try to do a login.

Currently it gives me a message saying [There is no account with the Username xyz]. I want to change the messaging to something else how do I achieve that?


Below is a link for overriding messages in the Okta Widget,

Thank You

Thanks Erick for your reply. Maybe my question wasn’t clear. I know how to override the messaging. I do for placeholders and also some of the other errors. But I am not getting the right property for error message where it says There is no account with the Username xyz. I tried looking for the error code aswell but am unable to find it.
