When logging in, an authentication code will be asked for.

We have implemented an authentication code check for users who haven’t set 2 factor authentication, in an effort to protect users from unauthorized access to their account.

A message with the subject below will be sent to your email registered with Chatwork.

Please use the 6 character code inside the message.


Subject: “Chatwork: Confirm your authentication code”


For users who cannot receive the above mail please try this.
