  3. 43 I forgot my passcode. What do I do?

    If you have forgotten your passcode, you need to delete and reinstall KakaoTalk.



    Please note that your data cannot be restored.

  4. 44 What kind of multimedia content can I send to my friends?


    You can share photos, videos, voice notes, your device contacts, URL links, locations and your friends' KakaoTalk profiles with other users.



    You can send up to 5 minutes of voice note and 300MB of video.

  5. 45 Can I use KakaoTalk on all Android phones?

    KakaoTalk is available for all devices running Android OS 2.3 or later.

  6. 46 What is a Secret Chat?

    Secret Chat uses end-to-end encryption which offers greater levels of privacy and bolsters security of user information. All messages are encrypted with a key held only by the participants of the chat so no third parties can access secret chat content without accessing the device itself. Secret Chat is currently available for 1:1 and group chatrooms. 

    In a secret chatrooom, features including free calling, polls, events and chatroom album are currently not available.


    [How to start a Secret Chat] 

    In 1:1 chatroom, tap the triple-lined menu on the top-right corner and select Secret Chat.

  7. 47 What is a public key?

    A public key is used to exchange secret keys which encrypt messages in a secret chatroom.

    There are three types of keys—a public key, a private key and a secret key.

    A secret key is used to encrypt messages in a secret chatroom. Secret keys of the participants will be exchanged once the secret chatroom is created. Public keys are used to encrypt secret keys and private keys are used to decrypt secret keys.

    Unlike the private key and the secret key, the public key is open to public and is used to determine whether the chat with other party is secured.



    You can check the public key image in the secret chatroom by going into the chatroom menu > Settings > Public Key. If the public key image is identical to your friend's, that means your chat is secured.

  8. 48 I get a message saying I can no longer use secret chat because the encryption information has been expired.

    If you reinstall KakaoTalk or change your mobile device, your encryption key will be changed. If your encryption key is changed, you will not be able to chat in your existing secret chatrooms. You will need to start new secret chats.

  9. 49 It looks different when I share a URL in the KakaoTalk chatroom.

    KakaoTalk v5.0.0 includes a new preview feature for URLs entered in the chatroom.












    A preview of your URL will be displayed so that you and your friends can easily see more of shared links while chatting.

  10. 50 Do I get birthday notifications for all my friends?

    No, you will only receive notifications for those who have entered their birthday information on KakaoStory and enabled the option to display their birthday on KakaoTalk profile.
    (To enable/disable this option, go to KakaoStory > Settings > Link KakaoTalk Profile > Birthday)
