When you use Save Between Sessions for database passwords and SSH passwords or pass-phrases, they are by default encrypted using a static key. The same is true for the Proxy password if you have specified one. For better security, you can specify a
Master Password that is then used instead of the static key to encrypt all passwords and pass-phrases. This way, only you know the information needed to decrypt the data. The algorithms used for encryption with a Master Password are also more advanced, minimizing the risk that the data can be decrypted by brute force.
