I lost all my account because of trusted the information here about authenticator HOT 2 CLOSED

You should have made sure that the keys were active on mac before backing up in + you should have made sure that from the first backup onwards they were all encrypted.

Your two-factor authentication tokens are only stored locally on your device, and are not backed up to iCloud or to an unencrypted iTunes backup. Here's a few things you could try:

• If you have an encrypted (iTunes or Finder) backup of your phone from before you reset it, you could restore it to recover your two-factor tokens.
• Many websites that offer two-factor authentication give a set of "recovery codes" to help you recover access to your account if you lose your phone. If you have recovery codes, you could use them to log in and disable or reset two-factor authentication on your accounts. (Some websites also support SMS-based two-factor authentication for account recovery.)
• If neither of the above works, you can try reaching out to the support for the website you no longer have access to and request their help recovering access to you accounts.
