Quick Start

Your address is created instantly

As soon as you open the site, a xxxxxxxx@tempmail.jp address is generated for you — no action needed.

Click the address field to copy it to your clipboard, then paste it wherever you need a throwaway email.

Save your password

A password is auto-generated alongside your address. It is stored on this device only — you'll need it to log in from another device or browser.
