Cookie Sync

Sync browser cookies to the cloud so headless browsers can use your logged-in sessions — per-profile isolation, auto-sync scheduling, and encrypted storage.

2 min read

Cookie Sync lets you securely upload cookies from your local Chrome to the cloud, so rtrvr.ai cloud browsers can use your logged-in sessions. Cloud automations can access authenticated sites (LinkedIn, Gmail, internal tools) without you sharing passwords or manually logging in to cloud browsers.

Cookies are encrypted and stored per-device in your private Firebase path. No other users can access them.

Profile-Based Isolation

Cookie Sync is scoped to the current Chrome profile. Each profile has its own cookie store, and sync only reads from the profile where the extension is running. Use separate profiles for separate accounts.

text
Profile "Work"     → syncs work Gmail cookies     → deviceId: device-work
Profile "Personal"  → syncs personal Gmail cookies  → deviceId: device-personal
Profile "Client"    → syncs client portal cookies   → deviceId: device-client

How It Works

  • Grant the "cookies" permission when prompted (optional, revocable anytime)
  • Browse your cookies using the search button — only the current profile's cookies appear
  • Check the domains you want to sync (e.g., linkedin.com, github.com)
  • Click "Sync All" or enable auto-sync on a schedule
  • Cloud browsers automatically restore cookies before running your workflows

Auto-Sync Scheduling

Cookies expire and rotate frequently. Enable auto-sync to keep them fresh. Choose intervals from 15 minutes to 24 hours based on how aggressively your target sites rotate session tokens.

Site TypeRecommended Interval
Banking / sensitive sites15–30 minutes
Social media1–6 hours
Internal tools12–24 hours
Auto-sync runs via Chrome Alarms, so it works as long as your browser is open.

Domain Selection

The cookie browser shows all domains with cookies in your current Chrome profile. Use the search bar to filter, then check the domains you want to sync. Selecting "google.com" includes all subdomains (mail.google.com, etc.).

Cloud Storage

Cookies are stored at a Firebase path unique to your account and device:

text
user_cookies/{userId}/{deviceId}/{domain}

Example: user_cookies/abc123/device-work/linkedin_com

Security & Privacy

  • Cookies are stored in your private Firebase path — no other users can access them
  • The "cookies" permission is optional and can be revoked anytime
  • You choose exactly which domains to sync — no automatic collection
  • "Clear Cloud Data" instantly deletes all synced cookies
  • "Revoke Access" removes the permission and clears all cloud data
For maximum security, use a dedicated Chrome profile for automation and only sync the domains you need.

Troubleshooting

  • Verify cookies are synced: check "last synced" timestamps in the domain list
  • Re-sync manually: click the refresh icon to force an immediate upload
  • Check the right profile: make sure you're syncing from the profile where you're logged in
  • Session expired: log back into the site in your browser, then re-sync
  • DeviceId mismatch: ensure your cloud workflow targets the correct deviceId
