# Purpose of Hideez Key

What problems does Hideez Key help you solve

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.
