Accessing Clipperz requires nothing more than entering your Clipperz credentials: your username and your passphrase.

But behind this very simple interface, a sophisticated authentication process is occurring: SRP, the Secure Remote Password protocol.

It’s a protocol developed at Stanford University by Tom Wu which is especially suitable for authentication over untrusted networks. SRP makes user account information stored on Clipperz servers absolutely unusable for any attackers, as well as for Clipperz staff.

Lock and logout

If you walk away from your computer for a few minutes, you can lock up your open Clipperz account by simply clicking on the lock link in the top left hand corner. You are not signing out, but the Clipperz interface “freezes” until you enter your passphrase.

If you plan to leave your computer unattended for more than a few minutes, it’s strongly recommended that you click on the logout link to completely sign out. No trace of your sensitive information will be left behind.
