# Mobile Application SSO
Mobile application SSO (Single Sign On, single sign-on) is similar to traditional Web-side SSO, which refers to multiple application systems, Users only need to log in once to access all mutually trusted application systems.Authing currently supports two forms of mobile SSO:
- Automatically detect the login status of associated apps on the same device
- Call up associated apps to exchange user information
# Automatic detection method
The automatic detection method is similar to the Meituan App. As long as one of the mutual trust systems on the same device is in the login state, it can detect the relevant user and prompt the user whether to log in with this account, thereby achieving single sign-on.
As shown below:
