Contexts
Use multiple accounts on the same website.
Open personal, work, client, or banking sessions together in one Lean window without switching full browser profiles.
What a Context separates
CookiesEach Context keeps its own signed-in sessions.
Website storageLocal storage and related site data stay with the Context.
Cache and networkConnections and cached resources do not use one shared Context pool.
Browser signalsCanvas, WebGL, audio, and deviceId present different signals.
Examples
Separation where profiles feel too heavy.
Personal and work
Keep two mail or collaboration accounts open side by side.
Client sessions
Use a separate signed-in session for each account you manage.
Banking
Keep financial sessions apart from general browsing.
Limits
A Context is not a VPN or another device.
All Contexts use the same public IP address unless you use a separate network tool.
History, passwords, and permissions are shared across the browser. Contexts are designed for session separation, not anonymity.
