About

OTP Inbox

Features
Read full description

OTP Inbox is a focused utility for receiving verification emails and finding one-time codes quickly. Use it when you need a separate inbox for app testing, QA workflows, signup checks, or short-lived verification flows. Create an inbox address, receive the verification email, open the message, and copy the detected OTP code without digging through your personal mailbox. Key features: - Receive verification emails in a clean inbox - Detect common OTP, login code, security code, and verification code formats - Copy detected codes quickly from the message list or detail screen - Keep multiple inboxes with local labels for different tasks - Search by sender, subject, message preview, or code - Review recent OTP history saved locally on your device - Block remote images to reduce tracking pixels in email content - Confirm external links before opening them - Clear cached messages, unread states, and code history from Settings - Switch between English and Vietnamese OTP Inbox is designed for low-risk, short-term verification and testing use cases. It is not a personal email service, business mailbox, password recovery mailbox, or long-term identity provider. Do not use generated inbox addresses for banking, health, work accounts, legal documents, password recovery, or any account where losing future email access would matter. The app stores inbox labels, cached messages, settings, and OTP history locally on your device. Email delivery and mailbox availability depend on the connected email provider, so some services may block, delay, or not deliver messages.
