I’m currently test driving PrivacyIDEA which is a very nice and versatile solution (Big thanks to Cornelius). For the end-user part I’m conducting some research on apps that can work in a reliable way with the PrivacyIDEA environment. Specifically I’d like to know how others on the forum are deploying/using end-user (IOS/Android) apps. Currently I’m doing some tests with Google Authenticator. My biggest concern is how users safely transfer the app to another phone in case they lost their phone or want to start using a new phone. There seems to be no way to backup the code and transfer it to another device. I also looked at the Authy app which seems to have an option to backup and restore the code. But I’ don’t want to rely on that.
