Bitgains advanced security makes it very difficult for hackers to access your wallet. When you sign up, you’ll need to use 3FA level security. After that, you’ll need to confirm your registration by clicking the link in your email. Once you have completed those steps, your decryption code will be saved on your cloud storage.  They have also implemented a guaranteed access solution called “BITGAIN PROTECT” that allows you to access your funds in extreme cases. You can reach customer service in case of lost account or wallet.
