Now, the sources of accounts are limited, and many accounts, after being purchased, are poorly managed and then stolen. Many people may have purchased their accounts that were previously stolen. Recently, the bug account has also been stolen. In view of this situation, let’s talk about how to minimize the possibility of secondary theft.
There are basically two kinds of accounts you can buy: one is the account password and a large list of cookies; the other is account password and two-factor authentication. Now the second one is more popular, so the main explanation is how this kind of account can reduce the secondary theft.
1-After logging in the account, it is recommended to bind your own email address and set it as the first choice. If possible, delete the email address of the original account owner. (The email bound to the account provided by some dealers is unique, so you can consider not deleting it)

2-Remove the original phone number and bind a new phone number at the same time

3-Change a new password

4-Remove unrecognized device information

5-Add two-factor authentication. Delete the authentication information set by the account provider if the two-factor authentication exists, and reset it.

Two-factor authentication can be done using the authenticator in Google Chrome extensions, or via the two-factor authentication within this site(https://2fa.veryfb.com). Mobile apps also have corresponding applications, but personally, I recommend using the web or plugin, as mobile management is less convenient than the other two options.
When the account is still in use, make sure not to delete the two-factor authentication plugins and apps, as you may not be able to log in yourself.
