Let us talk about the 2-Step verification in the Battle.net account. Always remember the following points before you add a phone number to your battle.net account:

  • Please don’t use one phone number for multiple accounts: It is very important to remember this as you have to use unique phone numbers for each battle.net account. You won’t be able to pass the verification process if you use the same phone number on different accounts.
  • Don’t use a temporary phone number: Please remember not to use a temporary phone number to verify your battle.net accounts. Temporary phone numbers are not meant to be used for 2FA purposes. If you don’t have a phone number, use your parent’s number.

Call of Duty Modern Warfare 2 has made it mandatory to add a phone number before playing the game to decrease the number of free accounts a user can create. This will reduce the toxicity and spam in the game. Some people are using new accounts to trash-talk other players. Remember to treat other players with dignity and respect if you are a gamer.
