Due to security and privacy reasons, every company that has passphrase protection is unable to access the passphrases. Therefore, if you lose your passphrases or incorrectly wrote them down initially, then you will lose access to your account, and there is sadly nothing our company - nor any company - can do to regain access to your account.

In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
