After numerous hacking claims regarding exchange sites and Myetherwallet
I thought to advice everyone to simply put to use ImToken app to control their Myetherwallet account
Then activate 2fa for every exchange site; all you have to do is
Download the google Authenticator app
Go to security and Authenticator settings
The site will generate a key for you ( FHFE3529KL8 ) ; copy the key, go to your auth app, click on the + sign, select add key. Type the name of the site, scroll to the next line and paste the key generated. THEN SAVE
You'll be seeing 6 digits codes every 5min or so. Use the code to login to the site.
Another important note while using 2FA is that you have to save the backup code of 2FA can log the logs or store them in 1 usb. In case of losing your phone or changing your phone. We will easily reinstall 2FA. Without backup code would be a big mess
