Sitecore: Setting the login page title
If you have multiple Sitecore sites or separate environments (e.g. Development, Test, Staging), a good way to tell them apart is by setting the title on the login page.
The best way of doing this is by creating a patch file with the following contents:
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
<sitecore>
<settings>
<setting name="WelcomeTitle">
<patch:attribute name="value">LOGIN PAGE TITLE GOES HERE</patch:attribute>
</setting>
</settings>
</sitecore>
</configuration>
