Get a verification code without giving out your email

A site asks for your email only to send a code? Give it a disposable address that only you can read, and copy the code as soon as it arrives.

In three steps

  • In your space, create an address, random or with an alias of your choice, and copy it.
  • Give it to the site, which sends its code or confirmation link.
  • The mail appears live; its code shows at the top, ready to copy.

nerdbox points out the code or the confirmation link that a mail seems to hold. It is an estimate: check it in the mail before you use it.

Wherever you are

  • In your space, in any browser.
  • On your phone, as a notification, once nerdbox is installed (how).
  • On the site’s page itself, with the Chrome extension, which also fills in the field.

A code nobody else sees

On a public disposable inbox, anyone who knows the address can read the mail, and the code with it. A nerdbox address is tied to your account: no other user can open it, or even learn that it exists.

When not to use it

An address lives 24 hours, 7 days at most if you extend it. Once it is gone, no password reset can reach it: give your real address to your bank, the administration, your health services and your work. And some sites refuse disposable addresses.
