What is two-factor authentication (2FA)?

Two-factor authentication (2FA) adds an extra layer of security to your login details. It is a security feature which utilises “something you know” paired with “something you have”. The first of these is a password and the second is a physical device, either a mobile phone, tablet, computer or a Yubikey. Two-factor authentication provides much stronger security compared to using only a username and password.

At the moment, we offer two different options on how to access your account via 2FA:

  • Authy Apps: This option utilises your mobile phone number to verify your account with an OTP (One-Time Password). OTP is valid only for a single use and cannot be used again for authentication. When registering, just choose the 'Authy' option and enter your phone number (e.g. 07712343456). You will receive a SMS asking you to download the Authy app and register your account with them. Once this is done, every time you log in to your account you will need to provide the OTP security token displayed in the app. For more information visit the Authy FAQ https://www.authy.com/faq.
  • YubiKey: This is a one-time password (OTP) generator device in form of a small USB stick. When registering just choose the "YubiKey" option and enter your YubiKey token. Every time you log it to your Coinfloor account you will need to provide the security token generated by your YubiKey. You can purchase a compatible YubiKey on Amazon. FIDO U2F Security Key is not a compatible key. For more information visit the YubiKey FAQ http://www.yubico.com/support/faq/
