Otto - 2FA Helper

Detects logins, fetches the 2FA code from your Gmail or Outlook inbox locally, fills it in, and tidies the email away.

Otto is a sleek, developer-centric browser assistant designed to eliminate context switching. By aggregating your inbound authentication and 2FA codes from your primary email channels directly into a clean, zero-friction dashboard, Otto keeps you focused on your active workspace. No complex interfaces. No data collection. Just your access keys, the moment you need them. ## Key Features Multi-Account Stacking: Link and manage up to 5 individual Google and Microsoft Outlook inbox streams simultaneously. Intelligent Key Extraction: Otto instantly parses inbound security traffic to surface verification codes, magic links, and OTPs in real time. Automatic Clipboard Sync: Click any extracted security code to copy it instantly. Global Smart Tidy: Toggle automated mailbox hygiene from your settings. Otto can automatically trash source auth emails immediately after you copy the key, keeping your primary inboxes completely clutter-free. Identity Isolation: Fully optimized for multi-profile workflows. Swapping connected accounts forces native account pickers, ensuring zero identity cross-contamination. ## The "Zero-Backend" Security Standard Otto operates on a strict local-first privacy framework. Direct Authentication: Your logins are handled safely via official Google and Microsoft Azure OAuth2 endpoints using isolated web-auth streams. Client-Side Architecture: Otto contains zero external database infrastructure or third-party analytical tracking. Your tokens and credentials never touch a remote server; they are stored encrypted inside your local browser runtime profile. Instant Memory Purge: Disconnecting an inbox stream forcefully invalidates the session token locally and destroys all related metadata instantly. ## How to Get Started Click Add to Chrome and pin Otto to your extension toolbar. Open the control panel and select Connect Provider to link your first Gmail or Outlook inbox. Manage settings globally using the integrated configuration menu. Watch your authentication loops drop to zero. ## Permissions Disclosure To deliver real-time verification processing locally, Otto requires secure authorization scopes (Mail.ReadWrite) strictly to fetch and clean inbound verification traffic. Otto adheres fully to the Chrome Web Store User Data Policy.
