Sign in with WhatsApp

Kodo has no password: you send a WhatsApp message prepared by the app, from your own number, and sign-in happens by itself.

Why WhatsApp?

Kodo does not use a password. To prove the number is yours, you send a WhatsApp message yourself, from that number. Only the person who holds the phone and the WhatsApp of that number can do it: no code is sent to you, so there is nothing to intercept.

Steps

  1. Enter your number, the one from the country where you live.

    « Your phone number » screen« Your phone number » screen

  2. Tap « Get the code on WhatsApp ». WhatsApp opens with a message already written, containing a code.

  3. Send the message without changing it, then come back to Kodo.

  4. Wait a few seconds. Sign-in happens automatically as soon as the message is received.

  5. Enter your 4-digit PIN, or use Face ID or your fingerprint if you turned them on.

The code in the message works only once and expires after a few minutes.

If it doesn't work

Nothing happens, or an error message appears? See the article « The WhatsApp sign-in message doesn't work ».
