TikTok FAQ

Aarhus University is following advice from the national Centre for Cyber Security not to use TikTok on work mobile devices. Below you can read some questions and answers about TikTok.

Is the TikTok app safe?


According to the national Centre for Cyber Security (CFCS), the TikTok app represents a risk to the privacy and security of both public institutions and individuals: 

“TikTok is an app that requests a wide range of rights and access rights on mobile devices. These access rights allow the app to collect a wide range of data and connect this data to the user’s identity. This applies to data such as the user’s location, contacts and browser history. When using TikTok, the user typically also gives TikTok access to the mobile device’s microphone and camera. Some of the data that TikTok is able to collect could also be used to spy on the user of the app.”

May I have TikTok installed on my AU mobile phone?


With reference to the assessment by the Centre for Cyber Security (in Danish only), Aarhus University has decided that TikTok may not be installed on AU mobile phones or tablets. 

See the article Say farewell to TikTok on AU phones

May I access TikTok via the browser on my AU computer or phone?


As a general rule, IT equipment issued by AU has been granted access to the university’s systems and network, so this equipment may not be connected to the TikTok service, cf. the above-mentioned security assessment.

May I use my private phone or tablet with TikTok installed to sign in to work-related apps (e.g. the Outlook app) with my AU staff account?


If you have TikTok installed on your private phone or tablet, you may not use this device to access any AU data. In other words, it is not possible to sign in to work-related Microsoft apps such as Outlook, Teams or OneDrive from a device on which TikTok is installed

May I use Microsoft Authenticator on a phone on which TikTok is installed?


In general, everyone at AU is discouraged from having TikTok installed on their private phone for the sake of their own and AU’s privacy and security. But the Microsoft Authenticator app is not included in this advice, because this app only accesses data in order to carry out two-factor authentication.

May I use the AU Find app on a mobile device on which TikTok is installed?


The AU Find app is accessible to the public and does not require you to use your AU account. 

Read more about this on the AU Find information page.

Can I use TikTok for research purposes?

Only if you take appropriate security measures. If you require access to TikTok for your research, you must first get approval from the relevant person in your research unit.

After this, you must contact your local IT support team to find a secure solution to access the app in a way that suits your specific research needs.

Are student workers also covered by the TikTok rules?

The recommendation issued by the Centre for Cyber Security (in Danish only) gives us all an opportunity to reconsider our use of TikTok. Not only for the sake of organisations like AU but also – and perhaps especially – for the sake of our own privacy and security.

According to the rules outlined above, TikTok may not be used on any equipment issued by AU. In addition, as members of AU staff, student workers may not use mobile devices with TikTok installed to access AU systems and data. 

For example, a student worker who replies to mails from an AU shared mailbox using Microsoft Outlook may not do so from a mobile device on which TikTok is installed.
