Storing your main seed phrase (24 words) on the cloud can pose significant security risks because online platforms are vulnerable to hacking and unauthorized access. Seed phrases are incredibly sensitive pieces of information; anyone who gains access to it can potentially control all the cryptocurrencies associated with that wallet.
While creating a passphrase (25th word) adds an additional layer of security to your wallet, it is crucial to remember that it functions as a second password. If your seed phrase stored in the cloud is compromised, the security of the entire wallet relies solely on the strength and secrecy of the passphrase.
To enhance security, consider storing your seed phrase offline in a safe and secure location. Using multiple methods for redundancy can be beneficial, such as writing it down on paper and keeping it in a safe deposit box, or using metal backup solutions designed to withstand physical threats. Always ensure that passwords, passphrases, and seed phrases are stored using security measures commensurate with the value they protect. Also, regularly updating and strengthening your security practices is essential to safeguard your digital assets.
