I see some confusion in the comments section:
SECURE YOUR ACCOUNT FOR 2X BATTLE PASS XP
Sign up for two-factor authentication to improve your account security and get two hours of 2X Battle Pass XP! We strongly recommend adding this extra layer of account protection, which requires a third-party authentication application when logging into your Activision account. Sign up at the CallofDuty.com 2FA page here.
Starting today, anyone who enables two-factor authentication will receive two 1-hour 2X Battle Pass XP Tokens as a reward. If you’ve already enabled the feature before today, your tokens will begin rolling out tomorrow, May 28th. Enjoy!
