Secrets of the edu-ID passwords

Since a few months now, edu-ID users  can secure their account with multi-factor authentication (Two-Step Login). However, currently 99.5% of all edu-ID accounts still rely exclusively on username and password authentication. It is unlikely to quickly change soon in the near future, despite the death of the password has been announced time and time again. The password remains the easiest, best known and – in many cases – the cheapest authentication solution. Therefore, the edu-ID team invests a lot of effort into assisting users to choose a strong password and to store it securely. Continue reading


Multi-Factor Authentication Reinforced

Since December 2018 the edu-ID login has supported multi-factor authentication in form of a two-step login that relies on SMS codes. However, receiving one-time SMS codes requires a mobile phone. Not all users want to add a mobile phone number to their edu-ID account. Furthermore, SMS messages generally cannot be securely sent. There is always the risk that somebody else intercepts SMS messages. Some edu-ID users also want to use multi-factor authentication for all their edu-ID logins but without entering a one-time code several times per day.
To address the above issues reported by the community, we extended the edu-ID two-step login in the following three areas…

Managing User Affiliation with the Organisation Administrator Interface

The edu-ID is a user-centric system in which users generally manage their account data themselves. And yet, some data relates to and is thus asserted by organisations like universities. Therefore, the edu-ID system provides several APIs for organisations so that they can manage data about users they are authoritative for. A new way to manage this data is the edu-ID administration interface for organisations, which is presented in this blog post.

Two or More Factors for edu-ID

A representative from a larger higher education organisation in Switzerland recently stated that they identify roughly 40 compromised user accounts on average per month. Extrapolating this number for  all Swiss AAI users, this number would grow to more than 1’000 compromised accounts per month. Many of them are probably not even detected. Many of them probably belong to young students who may not always take proper care of their credentials. But every now and then, also staff members and professors learn about the nightmares of impersonation of their digital identity. So, how can edu-ID support SWITCHaai services to enhance authentication security? Continue reading

There Can Be Only One!

As a child of the 80’s, of course I have seen the movie “Highlander”. In our “clone wars” (referencing Star Wars) against edu-ID duplicate accounts, I therefore remember the famous high lander quote “there can be only one”. Slightly adapted, this quote fits: “There can be only one edu-ID account per person”. Thanks to the automatic merging process described in this article, we now have the weapon in our hands to reach this goal.

Clone Wars

Duplicate user accounts on a single system are sooner or later causing a nightmare. One ambition of the SWITCH edu-ID has always been the prevention of duplicate user accounts. However, only a few weeks after the edu-ID launch in 2015 we already found indications for a couple of duplicate accounts. How did that come about and what can we do to prevent duplicate accounts?
