Here's some friendly tips on strengthening your passwords...
Add an extra layer of security:
Google Authenticator requires you to have access to your phone, as well as your username and password, when you sign in to your CoinCorner Account.
This means that if someone steals or guesses your password, they still can't sign in to your account because they don't have your phone.
Visit Settings in your CoinCorner User Area to enable Google Authenticator.
