Lost two factor authentication

[random123456]

Hello,
I play on Wrath of The Lich King 3.3.5a x5 realm. I had enabled two factor authentication on my account with an app Yandex.key, but I reinstalled my phone and lost the app :(. Now I cant log in to my account. I still have my email and everything, I just cant log in to my account since I dont have my app anymore. Can you help me to regain access to my account somehow?
Thanks in advance!

You should contact the Game Master of your realm (listed here) and ask for a form to fill.
After you've done with it - 2FA can be manually unbinded.
