2FA (or 2-factor authentication) is one of the first methods to protect your account where your personal data or the funds are kept. Please follow the steps described below in order to switch 2FA on your Changelly PRO account.

YubiKey is a helpful 2FA tool. It is based on the usage of a physical key that cannot be hacked remotely, making YubiKey a very reliable and safe instrument.

Changelly PRO supports all YubiKey devices pre-configured with Yubico-OTP function, namely:


● Yubikey 5 series;

● FIPS series;

● YubiKey 4, YubiKey 4 Nano, and YubiKey NEO.
