One Login, Many Apps: A Flutter Deep-Dive into Ecosystem Authentication

You open the Amazon Shopping app, signed in as usual. Then you download Alexa for the first time, and before you type a single character, it asks: "Continue as George?" No shared login screen. No password. Two independently-shipped apps, and one already trusts the other. This talk pulls that pattern apart and rebuilds it in Flutter, using the real native mechanisms behind ecosystem-level SSO rather than a shortcut. We'll cover how iOS Shared Keychain Access Groups and App Group containers let signed-together apps share session state, how Android's AccountManager and signature-level ContentProviders achieve the same thing without the now-deprecated shared UID trick, and why backend OAuth 2.0 token verification still has the final word regardless of what's shared on-device. Then I'll demo it live with two working Flutter apps, Shopfront and Companion, sharing one NestJS backend. Shopfront broadcasts a lightweight, non-sensitive session signal (never real tokens) via native platform channels. Companion checks for it on every launch and offers a "Continue as George?" prompt the user can accept, or firmly decline in favour of logging in manually, because ambient trust should never be forced trust. You'll leave with a working mental model of Keychain groups vs. App Groups, when signature-level Android permissions beat a deep link, and the production gotchas (signing mismatches, same-device testing, token-scope discipline) that trip people up the first time they try this for real.

Pressure To Performance: Unlocking the Human Operating System in an AI World

Pressure to Performance: Unlocking the Human Operating System in an AI World As artificial intelligence transforms the way we work, the greatest opportunity — and challenge — for organisations is not just adopting new technology, but understanding the humans who use it. In a world of accelerating change, uncertainty and increasing demands, leaders need to understand the human operating system: the psychology, neuroscience and behaviours that influence how people think, adapt, collaborate and perform. This talk explores how pressure impacts our ability to innovate, make decisions and connect, and why the future of high performance depends on creating cultures where people are resilient, psychologically safe and able to thrive alongside AI. Drawing on psychology, leadership experience and practical tools, participants will learn how to move from pressure to performance by developing greater self-awareness, regulating stress responses and unlocking the uniquely human capabilities that AI cannot replace — creativity, connection, curiosity and compassion.

About Krishna

I am Krishna Ruparelia, a leadership and resilience coach, and founder of Unshakable Resilience. I have over 25 years’ experience working at the intersection of psychology, people development and organisational performance, supporting organisations including Jaguar Land Rover, HSBC, Santander, Warwick Business School and Birmingham City University. My work focuses on helping high performers and teams understand the human side of performance — how our mindset, nervous system, behaviours and relationships influence our ability to adapt, collaborate and thrive in times of change. Alongside my corporate experience, I am a qualified yoga and breathwork teacher, bringing together evidence-based psychology with practical tools that help people build resilience, presence and self-awareness. I am passionate about exploring the relationship between technology and humanity, particularly as AI reshapes the workplace. I believe the future belongs to organisations that combine the power of technology with a deeper understanding of the human operating system — creativity, connection, curiosity and compassion.
