In normal cases you won't have to install developer releases. You are advised to go to the download area and grab the normal package as described in the past chapter. However there are situations where things are not working - if we confirm the problem, we fix it and generally release a developer release to test the fix. We proceed the same way with new features - we add them and create a developer release for those of you who like to experiment with them before the official release gets published.
To get the latest developer release navigate to Downloads -> Developer Releases -> Mydigipass. The latest release is always on top. Download the package and install it through the Joomla extension manager.
Please note: Having a backup is never a bad idea!
