If your account already uses email and password, sign in and open Account Settings → Change Password. Enter your current password, choose a new one and confirm the change.
If you cannot remember your current password, use Forgot Password on the sign-in screen and follow the instructions sent to your registered email address.
If you originally created your account with Google and do not yet have a Chatbot password, you can also use Forgot Password. Enter the same email address used for your Google account and follow the email instructions to create a Chatbot password. After setting it, you can sign in with either Google or your email address and password.
For an account created with Apple, continue using Apple sign-in unless email-and-password sign-in has already been set up. To change the password for your Google or Apple account itself, use that provider’s account settings.
