I want to change the message that pops up during implementation of Basic Auth.The current default message is:

[![enter image description here](https://i.stack.imgur.com/ZMBql.png)](https://i.stack.imgur.com/ZMBql.png)

> 
> Server requires a username and password.
> 
> 
> 

Something that would be more accurate for me is :

> 
> Server requires an Email and Password.
> 
> 
> 

My problem is that i can't find or don't know where this message is set and if it can be changed. Most of the questions online are about Basic Auth implemention but this is not my problem -- i can implement it very fine. I just need a more accurate response for the user.

Here is how i force an authentication window using echo:

```
c.Response().Header().Set(echo.HeaderWWWAuthenticate, `Basic realm="Your Email is your Username"`)
return echo.ErrUnauthorized

```

NB: Only Firefox shows the realm message. Both Chrome and Opera do not.
