Identity & Session
Control browser branding, locale and timezone, cookies and storage, and account isolation across contexts and sessions.
New to this section? Start with Per-Context Fingerprint.
Use This Section When You Need To
- You need separate identities for multiple accounts inside one browser process.
- You want browser brand, locale, timezone, and User-Agent signals to stay coherent.
- You need to seed or inspect cookies, history, bookmarks, or local storage.
Recommended Reading Order
- Per-Context Fingerprint - Assign isolated fingerprint bundles to BrowserContexts inside one browser instance for lower overhead and stronger account separation.
- Multi-Account Isolation - Run multi-account browser isolation with per-context fingerprints, proxies, and controls that reduce cross-account linkability.
- Browser Brand Alignment - Switch browser brand identity (Chrome, Edge, Brave, Opera, Chromium, WebView) with consistent fingerprint protection across all identity surfaces.
- Timezone, Locale, and Language - Configure timezone, locale, and language to protect geographic identity and keep it consistent across browser APIs.
