The 57 per cent of respondents who did actually know the purpose of the PIN often used complex alphanumeric passwords, which they saved in a password manager.Ĭommunication not suitable for new target groups They also often assigned short PINs that only consisted of numbers.

It takes place from 8 to 10 August as a virtual conference. The results of the online survey are being presented at the USENIX Symposium on Usable Privacy and Security by Daniel Bailey and Philipp Markert from HGI together with the US researcher Adam Aviv. The researchers collected data from 235 Signal users, mainly from Germany, the USA and the United Kingdom, from the beginning of September to the beginning of November 2020. However, almost half of the respondents assumed that there was another purpose, such as that the PIN would be used to unlock the app. Signal uses the PIN for an encrypted cloud backup of contact details, settings and profile information as well as – on request – to authenticate the user when they first log in. This was shown in a survey by the Horst Görtz Institute for IT Security (HGI) at Ruhr-Universität Bochum and the George Washington University.
