Is there a way to remove all the Yunohost branding, like the favicon, the icons, etc?
Hi, there is no easy way to theme YunoHost at the moment.
However, you can manually change the HTML and CSS files to change the names and logos: https://github.com/YunoHost/SSOwat
The logo can be replaced by another here: https://github.com/YunoHost/SSOwat/tree/unstable/portal/assets/img
The different pages of the portal are here: https://github.com/YunoHost/SSOwat/tree/unstable/portal
Just change the locales accordingly for instance: https://github.com/YunoHost/SSOwat/blob/unstable/portal/locales/fr.json
Customize the CSS: https://github.com/YunoHost/SSOwat/tree/unstable/portal/assets/css
