You do not need to create an account or install anything to sign a cause. All you need is an email address you can check right then.

The whole journey in three minutes: reading the cause, signing, confirming the code, boosting, sharing and checking your certificate.

Where you sign

A cause opens from the link you were sent, or from the public listing at causfy.com/causas. On the page you see how many people have signed, what is being asked and of whom, and the Sign this petition button. On a computer it sits in the card on the right; on a phone it stays fixed at the bottom of the screen.

A cause page: the petition, how many signatures it has and the button to sign.

The steps

1

Fill in the form

Press Sign this petition. A window asks for two things: your first and last name and your email. Below are two optional boxes:
  • Do not show my name publicly (sign anonymously): your signature counts just the same, but your name does not appear on the cause page.
  • I want to receive this cause’s updates by email: only if you want the organiser to tell you how it is going.
By pressing the button you confirm that you are at least 14, or the minimum age in your country to give consent, and you agree that we verify your email.
Sign this petition window with the fields First and last name and Your email, the boxes to sign anonymously and receive updates, the consent sentence and the green Sign this petition button

The signing window: name, email and the two optional boxes.

2

Enter the code you receive by email

We send a 6-digit code to the email you typed. Enter it on the Check your inbox screen and press Confirm signature. If it does not arrive, check your spam folder and use Resend code; the button becomes active after a few seconds.

Your signature now counts

You will see Your signature now counts! and, right below, your signature certificate and the buttons to share the cause. You will also receive a confirmation email with links to download the certificate or withdraw your signature later.
If you close the window halfway through, your signature does not count yet and you will have to start again. The portal warns you before closing.

Worth knowing

  • One signature per email and cause. If that email has already signed this cause, the portal tells you and does not count it twice.
  • A check that you are a person. A bot protection loads when you sign. You do not have to do anything; only in rare cases does it ask you to try again.
  • Signing is declaring. If the organiser wrote the petition with your details inside (“I, your name, resident of your city, ask…”), those gaps are filled with what you typed when you sign, and that is how it appears on your certificate.
  • No account, no password. The email with the code is the whole check. That is why it matters to type the address correctly.
  • It works the same on a phone, and that is how most people sign.

What happens next

Your signature is added to the cause’s counter and, unless you marked it as anonymous, your name appears among the latest signers. Whoever organises the cause receives your name and your email so they can deliver the petition and, if you asked for it, send you updates. Nothing else: what is stored and how to delete it is explained in Withdraw your signature and your data.
