# Purpose of Hideez Key Electronic key Hideez Key is designed to authenticate users on electronic devices, such as PCs; storing encryption keys, passwords, logins and other personal data; performing encryption, hashing and electronic signature operations; generating one-time passwords (OTP); and identifying users using the RFID protocol (125 kHz HID and Em-Marine standards). Hideez Key requires the installation of the Hideez Safe software. Using Hideez Key along with Hideez Safe allows users to perform the following operations: * Lock/unlock access to a PC, based on an estimation of distance using the radio-signal indicator for the Bluetooth signal (RSSI). * Store user credentials for various programs and web-services. * Generate one-time passwords for services that use two-factor authentication specification RFC 6238, such as Google, Microsoft, Dropbox and Facebook. * Perform encryption operations and electronic signatures according to the AES-128, RSA-1024 and ECC standards inside Hideez Key. * Update Hideez Key firmware using a Bluetooth channel. * Remotely (by Bluetooth) turn off the computer. * Run the executable file. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
