How to receive verification codes (OTP) with a temporary email

Updated October 7, 2026

A temporary email is handy when you need a verification code to try an app, download a file or join a forum without handing over your real address.

The steps

1. Open EmailPuff. A random address is ready, or type any name you like into the address box.
2. Click Copy.
3. Paste the address into the email field on the site you are signing up for and request the code.
4. Go back to the EmailPuff tab. The new message appears in the inbox on its own, highlighted in green.
5. Click the message to read it, then copy the code or click the confirmation link.

Tips so you never miss a code

• Turn on sound and notifications under Settings on the home page. You will know as soon as mail arrives, even from another tab.
• Keep the EmailPuff tab open while you wait. Closing it does not lose mail, but you will not be alerted.
• Use the code right away. Most verification codes expire within 5-15 minutes.
• Remember the address if you need to come back. Recent addresses keeps the ones you have used in this browser.

When not to use a temporary email

So never use a temporary address for:

• Banks, payment apps, or any account that holds money or card details.
• Work, school or government accounts.
• Any account you want to keep long term, because you will need the email later to reset your password.
• Anything that sends personal information by email, such as documents, contracts or medical results.
