Save sensitive data (eg. for autologin)

Hi,

i would like to add a autologin-function to my new App. I’m not really sure where i should save the Login-Data.

The Storage-API will save it directly and readable on the filesystem, correct? Or do i have to connect to the iOS- and Android-Preferences API just like https://github.com/bolav/fuse-usersettings ?

Thanks for ideas.

Hi , For my login , save the id and pass in a file.txt , instal the app in my mobile and try to see this file and I can’t , maybe the people of fuse check the secure file or say that is secure with one file.txt
