How to change the title and the login box

[gmbasile]

Hello I write to know if someone can give me a hand with this:
Need to replace the title (head) which is default and appears in the browser (ex. Roundcube Webmail:: Welcome to Roundcube Webmail) on the other.
Also need to change the title that appears in the login box (ex. Welcome to Roundcube Webmail) on the other.
I searched all files and their contents but found nothing, anyone know what the file and line must be edited to make the change.
I hope someone can help me.
Greetings

Gonzalo
