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.
