Registration & Installation myCSS / myCSS-App

Protecting your data is our top priority, which is why we opted for a two-stage registration process for myCSS. This unfortunately makes installation a little difficult, but in return promises maximum data security.

Once you have registered, we will send you a letter containing your personal activation code. You will receive it within five working days, and can then complete your registration.

Registering on myCSS

  • First go to myCSS on your computer and set up a user account.
  • Once you have received your activation letter, log in using this user account.
  • Enter your mobile phone number and then type in the activation code contained in the letter.
  • Then enter the 6-character SMS code that you receive from CSS (+41 79 807 00 70).

You have now completed the registration process. If you log in to the myCSS client portal immediately after registering, you will receive a new SMS code.
From now on you can also install the myCSS app.

Installing the myCSS app

If you do not yet have a myCSS user account, please register via your computer.

If you already have a myCSS account, and have successfully downloaded the myCSS app to your smartphone, proceed as follows:

  • Open the myCSS app.
  • Accept the user agreement for the myCSS app.
  • Enter your email address and personal password.
  • Enter the SMS code that you receive.
  • Define your personal app code – it's best to use your password.
  • Activate Touch ID / Face ID (if your smartphone supports this function)

The myCSS app is now linked to your account. To access your client data via the app, all you have to do is enter your personal app code.

Frequently asked questions

The app code that I receive by text message is only 6 characters long. What am I doing wrong?

The app code (8 characters) is not the same as the SMS code (6 characters). You are probably mixing up these two codes.

We recomend that you first complete your registration on myCSS, and then install the myCSS app. This should ensure that you are using the right code in the right place.

Why can’t I find the myCSS app in the Google Play Store or App Store?

The myCSS app is only available in the Google Play Store or App Store in Switzerland and neighbouring countries. You can change these settings on your phone, however.

Instructions for Apple

How can I register a new mobile phone number?

Go to "Personal data / Settings / New mobile number" and follow the instructions. We will send you a new activation code by post in order to protect your privacy. You can then use it to change your mobile number.

For security reasons, it is not possible to change the mobile number via the app.
