Eidoo is an HD (Hierarchical Deterministic) wallet. A deterministic wallet is a system of deriving keys from a single starting point known as a seed. The seed allows a user to easily back up and restore a wallet without needing any other information and can in some cases allow the creation of public addresses without the knowledge of the private key. Seeds are typically serialized into human-readable words in a seed phrase.
HD wallets represent the strongest security system compared to custodial services or wallets that use a simple password.
The answer depends mostly on how you manage your wallet. In fact, every wallet contains a set of private keys without which the owner cannot have access to funds. The biggest danger in security is you perhaps losing the seed or private key or having them stolen.
the only way to restore your wallet is through the 12 words passphrase (seed) that was provided to you the first time you opened the wallet. For your financial security and to avoid any kind of cyber attacks, Eidoo does not hold a copy of the seed of its customers, moreover, there is no server where this information is stored, there is no way for Eidoo to proceed with the restoration of your wallet.
Without your seed or your private key, you will never see your cryptocurrencies again.
This is a security worldwide standard for digital currency wallets.
