Activate additional mobile telephone for e-banking login

You have a new mobile phone, and would like to activate this for your e-banking access, in addition to your existing mobile phone.

Step-by-step instructions

Important: You will need your existing mobile phone, with its already activated access, in order to set up access for your new phone.
Go to the e-banking login page and enter your contract number and password.
You will see a coloured mosaic. Scan this with your old mobile phone, enter the code, and select «Activate an additional device». Then click on «Login».

Go to the activation letter (letter with mosaic pattern) sent to you with your initial access data for e-banking. If you no longer have this letter, you will have to order a new activation letter.
Scan the CrontoSign Swiss App mosaic pattern in the activation letter with your new mobile phone and enter the code in the «Code» field. Click on «Continue» in the app.
Click on «Verify» on the screen.
You will see a new mosaic pattern appear on your screen. Scan this with your new mobile phone and enter the code. You have the option of providing a name for the mobile phone number in question.
Click on «Register». You will receive confirmation that the authentication process was successful.
Click on «Continue» and you will be logged into e-banking.
