Each Bitcoin wallet must have different layers of security and different ways of securing it. But on average, they provide an option where you can add 2 Factor Authentication to give an extra layer of security to your wallet. 2 Factor Authentication is usually a verification via SMS pin that will enter the mobile phone number you registered when you created a wallet, or a Google Authenticator pin that you can install on your laptop or on your smartphone. As a result, every time you want to login to your wallet, you should be able to enter your e-mail address, password and SMS pin or GA pin to access your wallet. Whether or not your wallet is safe depends on your own. Learn how to secure your wallet early because different from a Facebook account that only contains personal information, your Bitcoin wallet can be worth hundreds of thousands to billions of dollars. Very unfortunate when taken over by others, is not it?
