Premium Security Features
TempNova goes beyond simple throwaway mailboxes. Discover the features that make it the ultimate privacy and developer tool suite.
A Complete Privacy Utility Suite
Most disposable email tools offer a single inbox and nothing more. TempNova was built with a fundamentally different philosophy: privacy should be comprehensive, not piecemeal. Every feature in TempNova addresses a specific real-world privacy risk — from email tracking pixels that leak your location, to VoIP-rejected phone number verification, to credential-exposing registration forms.
The features below cover the full spectrum of modern digital identity risk management: anonymous email inboxes, real SIM-carrier phone numbers, self-destructing encrypted links, sandboxed email rendering, and a complete developer API for automated testing pipelines. Every component is free to use with no registration required. The platform is designed around a stateless, zero-logs architecture — meaning no personal data, email content, or browsing history is ever stored on our servers.
Instant TempNova Engine
TempNova is connected directly to high-reliability temporary mail API servers with sub-second response latency. When you click "Generate," our engine requests an available domain, creates a random inbox address, and establishes your session token — all in under 1.5 seconds. Auto-refresh polling continuously checks for new messages every 10 seconds so you never miss a verification email or OTP code.
OTP Auto-Highlighting
Our intelligent OTP parser automatically scans every incoming email's subject line and body for one-time password patterns — 4, 5, and 6-digit numeric codes, alphanumeric verification tokens, and confirmation PINs. When detected, the code is displayed prominently at the top of the email viewer in a highlighted chip with a one-click copy button, eliminating the need to scroll through email HTML to find your code.
Concurrent Inboxes (Multitabbing)
TempNova's multi-tab inbox panel lets you run up to 5 fully independent temporary email addresses simultaneously in a single browser session. Each inbox has its own address, countdown timer, and live message feed. This is ideal for developers testing multi-user registration flows, QA engineers validating parallel signup scenarios, or privacy advocates managing multiple service registrations without identity crossover.
Fake Identity Generator
Every TempNova inbox is paired with an automatically generated pseudonymous identity profile: a randomized full name, date of birth, fictional occupation, mock street address, and an associated username suggestion. This allows you to complete full registration forms — including fields that require personal details — without entering any real personal information. For design and testing purposes only; not for fraud.
Credit Card Mockup Generator
Design visually accurate, non-functional credit card mockups for UI prototyping and payment flow design presentations. Generate card numbers validated against the Luhn algorithm, configure card network (Visa, Mastercard, Amex), expiry dates, and CVVs for realistic test data. All generated card data is fictional — no real financial instruments are created. Perfect for payment UI wireframes and checkout flow demonstrations.
Sandboxed Iframe Reader
TempNova's email viewer renders all incoming HTML messages inside a fully sandboxed iframe container. This multi-layer protection system strips external image tags (tracking pixels), removes script elements, enforces Content Security Policy headers blocking external resource loading, disables form submissions, and prevents top-level navigation hijacking. The result: you can safely read any HTML email — including suspicious newsletters — without leaking your IP address, device data, or reading timestamp to the sender.
Browser Push Alerts
Enable optional desktop push notifications to receive an instant browser alert the moment a new email arrives in any of your active inboxes — even when TempNova is running in a background tab. This eliminates the need to manually check the dashboard while waiting for a verification email or OTP code, making TempNova feel like a native app notification experience. Works on Chrome, Firefox, Edge, and Safari on macOS.
International SMS Number Pool
TempNova's virtual phone number library covers multiple countries including the United States (+1), United Kingdom (+44), Germany (+49), France (+33), Canada (+1), Netherlands (+31), Brazil (+55), India (+91), Japan (+81), Australia (+61), and more. Select your target country before generating a number to receive a locally-prefixed virtual line for completing geographic OTP verification gates. The country pool updates based on carrier availability.
Real SIM-Carrier Routing
Unlike VoIP-based virtual number services that are automatically detected and rejected by WhatsApp, Discord, Stripe, and Google, TempNova routes all virtual numbers through physical SIM-carrier gateways. These numbers present to verification systems as genuine mobile phone connections with real carrier routing metadata, prefix structures, and STIR/SHAKEN attestation signals — dramatically increasing compatibility with platforms that enforce strict anti-VoIP filters.
Developer API & Webhook Support
TempNova provides a full REST API for programmatic inbox creation, message fetching, OTP extraction, and virtual number management. Authenticated via JWT, the API supports up to 8 requests/second and integrates seamlessly with Playwright, Cypress, Selenium, and GitHub Actions CI/CD pipelines. Configure webhooks to receive real-time push notifications the moment an SMS or email arrives — eliminating polling delays in automated test workflows.
Stateless Zero-Logs Architecture
Every piece of session data in TempNova — your generated email address, inbox JWT token, received messages, and virtual number history — exists exclusively in your browser's localStorage and Zustand state. Nothing is permanently stored on TempNova's servers. When you release an inbox or clear your browser data, all records are permanently and irreversibly destroyed. This architecture means even a server compromise cannot expose your email history, because the data was never there.
Chrome Browser Extension
Right-click any email input field while browsing the web and select "Insert TempNova Mail" to generate and populate a temporary address instantly.
Webhooks & API Integration
Automate QA testing. Configure webhooks to forward incoming messages in JSON format to your developer servers automatically.
