How to Create a Seamless Mobile SSO (Single Sign-On) Experience in iOS

How to Create a Seamless Mobile SSO (Single Sign-On) Experience in iOS

On an iPhone, when we log in to an app, we click a login button, and a website pops up to verify our credentials. Once verified, the website then redirects back to the app, and you are logged in. This familiar Single Sign-On (SSO) pattern is frequently referred to as the redirect flow for authentication. The use of a web browser for auth in this example is considered a “Best Current Practice” for security and...

Native SSO: Desktop and Mobile Apps Single Sign-On

When you hear SSO (Single Sign-On), you probably immediately think of web apps, and how you only need to sign into one web app first, then all other web apps give you seamless access.

Mobile Development with Ionic, React Native, and JHipster

Mobile Development with Ionic, React Native, and JHipster

Mobile development offers a lot of options. To develop native apps, you can use Java or Kotlin on Android. On iOS, you can use Objective C or Swift. There are other options, too. You can build hybrid mobile apps and Progressive Web Apps (PWAs). Hybrid mobile apps are those created with web technologies (HTML, JavaScript, and CSS) that look like native apps. PWAs have the ability to work offline and act like mobile apps too....

Build an App for iOS and Android with Xamarin

Xamarin is a cross-platform technology that makes it possible to build native applications for Android and iOS using a single, shared codebase. Like other technologies such as React Native and NativeScript, it allows development teams to spend less time writing code for both platforms. Xamarin is open-source (and free). Under the hood, it uses Mono (a version of the Microsoft .NET runtime), so Xamarin apps are usually written in C#. You can build Xamarin apps...
