Single sign-on (SSO) is defined as login once, logged in all apps. If you have multiple mobile apps or websites that wants to streamline the user experiences. You can configure your apps to turn on the SSO feature, so the end-users only have to enter their authentication credentials once.

There are multiple ways to achieve Single Sign-on, with various pros-and-cons:

Related Feature
Technical Remarks

SSO between Websites with the same apex domain

Requires all of the websites with the same "root domain" (e.g. app1.example.com and app2.example.com)

SSO between Mobile Apps and Browsers

Requires the use of ASWebAuthentication and Custom Tab on iOS/Android respectively

SSO between two independent mobile apps

Based on OIDC App2App

SSO from a Mobile App to Website

Open a URL from Mobile App and pass the user session along, based on OIDC Token Exchange

SSO between Mobile Apps from the same publisher

Keychain Sharing / Android Account Manager ( if you need it)

Requires both apps published by the same publisher from App Store.
