Remus has a good support on storing sensitive information like passwords. If you want to store any data in an encrypted manner, you can create a new so called "Encrypted Information project", All created information units created under this project are encrypted via an virtual filesystem and are not visible until you have initialized the appended security provider for this project. Browsing the raw data e.g. the stored XML files on your harddisc is also not possible.
Additionally Remus provides an information type called "Password", where you can store several credentials and let Remus fill them into the login form of any webpage or other application.
At first you have to create an enrypted project. Go to New → Enrypted Information Project and create a new project. Encrypted projects have a small lock-decorator in your navigation structure (see picture).
