Instant temporary email, smart per-site aliases, one-click autofill, OTP detection, and a full-height inbox side panel.

SecureTempMail gives you a fast, private way to create temporary email addresses and receive emails without filling your primary inbox with unwanted messages.

This makes it easier to identify where an address was used and manage temporary sign-ups without repeatedly typing or copying addresses. ### One-click autofill When a website asks for an email address, SecureTempMail makes it easy to insert your temporary address without switching tabs or copying and pasting manually. ### OTP detection When supported verification or OTP messages arrive, SecureTempMail can identify the relevant code so you can find it quickly while completing a sign-up or verification flow. ### Full-height inbox side panel Check incoming temporary email without leaving the page you're working on. The side panel provides a convenient way to view your inbox and incoming messages while keeping the current website open. ### Useful for • Website and app testing • Developer testing and QA • Email verification workflows • Temporary sign-ups • Free trials • Downloading resources that require an email address • Keeping promotional messages out of your primary inbox • Testing email-based user flows • Situations where you don't want to use your personal email address ### Built for temporary use Temporary email addresses are designed for short-term communication and verification workflows. Do not use temporary email for important accounts, password recovery, financial services, or other situations where you need long-term access to the mailbox. SecureTempMail is designed to make temporary email easier to create, use, and manage directly from your browser.

When you have securetempmail.com open and the extension active in the same browser, both now show and use the same live inbox instead of generating two different addresses — no sign-in required. Whichever surface you're actually using stays authoritative; a fresh default on one side never silently overwrites an inbox you're actively using on the other. Fixed The popup's "expires" countdown was inverted, showing nonsense like "expires −3626s" instead of a real countdown (e.g. "expires 58m"). Every user's popup was affected, every time.
