Profile Auth Keeper

Automatically re-authenticates your Chrome profile when Google sign-in expires

Profile Auth Keeper silently monitors your Chrome profile's sign-in status and automatically re-authenticates you when your Google session expires. **How it works** Every 5 minutes, the extension checks whether your Chrome profile's OAuth2 token is still valid. If your session has expired, it opens the Google sign-in page, fills in your saved password, and submits the form — then closes the tab and notifies you once you're signed back in. **Features** - Fully automatic — no clicks required when your session expires - Password stored locally in your browser, never transmitted anywhere - Circuit breaker: pauses after 3 consecutive failures and alerts you to intervene - Skips 2-factor authentication challenges (only handles password re-entry) - Badge indicator shows re-authentication status at a glance **Privacy** Your password never leaves your device. The extension has no backend, no analytics, and no tracking. See the full privacy policy for details. **Permissions used** - Google account access (OAuth2) — to detect when your session has expired - accounts.google.com — to automate password entry on the sign-in page - Tabs — to open and close the sign-in page automatically - Notifications — to alert you when sign-in succeeds or requires your attention - Storage — to save your password and extension state locally
