A login screen hangs open. Minutes pass. The user walks away. You lose control of the session.
The onboarding process session timeout enforcement isn't just a feature. It is a line of defense for security, compliance, and user trust. Without it, stale sessions become a risk vector. Tokens linger. Sensitive data remains exposed in memory or browser storage long after your user has disengaged.
Session timeout enforcement begins with defining clear limits. Measure inactivity in seconds or minutes, not guesses. Decide what inactivity means in your system: no HTTP requests, no DOM events, no API calls. Track these events in real time. Your onboarding flow must integrate this detection from the first screen to the final confirmation.
Once detected, end the session cleanly. Invalidate tokens server-side. Purge local caches. Redirect to a secure re-authentication page. Alert the user promptly, so they understand why they must log in again. This transparency prevents frustration and supports trust.
