Two-factor authentication is still one of the most effective methods of protecting your account. One of the most common ways to hack WordPress sites is to brute force passwords.
CleanTalk Security plugin for WordPress already has two-factor authentication by sending an authorization code to the email account.
We have now expanded the two-factor authentication options and added the Google Authenticator option.
Now you can choose the most convenient 2FA option for you.
