Giving users access to the User Profile preferences via the mobile site/skin could be valuable. Seems like something we could investigate further.
From a discussion about being able to access desktop settings via the mobile site/skin (https://www.mediawiki.org/wiki/Topic:Upsnns63k0n6xlfc):
@AHollender (WMF) While I would say all of tabs, the one I am mainly focused on using the "User profile" tab. It feels so cross platform with all the ways it used depending on what platform it is. They have features such as the ability to change ones password, change in signature exc, and not so much the font style or other computer exclusive platforms.
