# Otpkey Authenticator

The Otpkey Authenticator app creates authentication credentials, such as OTP, Push-based authentication, and QR code-based authentication, to verify users' identities when needed. Similar apps include Google Authenticator and Microsoft Authenticator apps.

For example, if you use two-factor authentication on GitHub to enhance security, you need to use an OTP app on your mobile device such as the Otpkey Authenticator app.

The Otpkey Authenticator app is a multi-factor authentication app developed and distributed by Certchip as part of the OTPKEY authentication product line. This app is available on the following platforms and can be installed on your device for free through each of the stores below.
