Hello, I've formatted my phone without removing the 2FA. I don't have neither the recovery code, so I cannot restore the 2FA.
Can you help me?
Two-factor authentication sadly can not be deactivated by TeamViewer for free users. If you lose your recovery key and 2-factor you will also lose access to your TeamViewer account
Here you can also find some information on how to deactivate the function in case you find your recovery code. http://www.teamviewer.com/en/help/402-How-do-I-activate-deactivate-two-factor-authentication-for-my-...
Hope it will be helpful for you.
Yuri has flagged me to assist you with this.
Can you please PM (Do not post publicly) the email address of the account you lost the recovery code for?
I will then have to raise a ticket for you as this can only be done by a Moderator.
Once the ticket is raised, I will send you an email to the email address associated with the account to sort this for you.
Your account will need to be deleted so you can re-use the same account and unfortunately we cannot recover any of the information saved in it.
For any other free users reading this, please PM a Moderator with the email address and tell them it's for 2 factor.
For any paid users with this issue, contact support.
