Screen keyboard

If you prefer a pointing device over the keyboard, turn on the Screen Keyboard from the accessibility menu ().

You can also use the screen keyboard to protect against hardware keyloggers by avoiding to use the actual keyboard.

If a keylogger has been physically installed on the computer, your passwords, personal information, and other data typed on the keyboard could be stored and accessed by someone else, even if you are using Tails.

For an example, see KeeLog: KeyGrabber forensic keylogger getting started.

Keyloggers are more likely on public computers, in Internet cafés or libraries, and on desktop computers, where a device is easier to hide.

Reducing risks when using untrusted computers
