United States-based cryptocurrency exchange Kraken announced that two-factor authentication is now mandatory for the exchange’s users.
Nick Percoco, chief security officer at United States-based cryptocurrency exchange Kraken, announced that two-factor authentication (2FA) is now mandatory for the exchange’s users in a post on the company’s official blog published on March 26.
2FA, in this case, is an additional component needed to access an account. Often 2FA requires the user, after entering their login information, to also enter a one time password (OTP) received via SMS. Per the announcement, Kraken supports Google Authenticator  and YubiKey as 2FA implementations.
YubiKey is a hardware device dedicated to generating OTPs, while Google Authenticator is a smartphone app meant to do the same.
