  2. Registration must match the registered login. The relevant, SuisseID, SwissID, ZUGLOGIN or Login Geneva login methods apply.

  3.  The instructions under “Forgotten password” lead to the renewal of the personal password. The new password is either sent to you as an SMS code, or you can enter it directly if you answer the security question correctly.

If you are still unable to register, the customer service department will be happy to help.

In your personal IncaMail account, you can enter the new e-mail address under settings in the “e-mail addresses” section. As soon as you have added the new address, an e-mail is automatically sent to this address with the activation code. By entering this activation code in the settings, registration of the new e-mail address is complete. You can now use the usual password to open all IncaMail messages to the previous and new e-mail addresses. A registered e-mail address and the password is sufficient to register for IncaMail. If you wish, you can also open a new IncaMail account using the new e-mail address.

IncaMail messages cannot be forwarded to other e-mail addresses. To receive IncaMail messages at the new e-mail address, the sender must be notified accordingly.
