Multifactor Authentication Setup

What is multifactor authentication?

You probably know it from your private online banking or already from Microsoft Office 365 or Teams at UZH. When logging into an online application, you have to log in with a second factor in addition to your username and password.

Why multifactor authentication?

Protecting access to online applications and the information saved therein via user name and password alone is no longer sufficient today. The UZH is also not safe from cyber attacks. Therefore, relevant online applications with sensitive data and information are gradually secured with multifactor authentication. After Office365 and Teams, these are in particular the SAP web portals and other business-critical online applications.

How does multifactor authentication work at UZH?

You can choose between various second factors that can be used. On your mobile phone, you can use an authenticator app, receive a verification code via SMS or a phone call. You can also use a landline phone to get the verification call.

How to set up multifactor authentication?

If you already use Microsoft Office365 or Teams at UZH, you have already set up multifactor authentication for yourself and can also use it for other applications. If this is not the case, you will be supported in setting up a second factor via a guided dialog when you log on for the first time with multifactor authentication.


  • For home office use, we recommend the use of the mobile phone.
  • Authenticator app (e.g. from Microsoft: Download): The app must not be deleted after registration. Multifactor authentication must be confirmed regularly. The Authenticator app must also be reconfigured after a device change.
  • You can check and manage your settings for multifactor authentication here: Define the standard login method, change the login method, store additional login methods.
  • Recommendation - Store an additional login method. You can also log in if the selected access is not available (e.g. if your mobile phone is defective or lost).
