Hardware wallet seed security

A seed phrase is the master key to your crypto and it must be guarded like a living treasure; never share your 24-word seed with anyone, never photograph it, and never store it where others can view it. Write the words by hand on a durable medium and keep that paper or metal backup in a physically secure place such as a home safe or a safety deposit box, and consider two or three geographically separated backups so a single disaster cannot wipe them all out. Generate the seed phrase yourself on a new, trusted hardware wallet and never use a preconfigured device, because only you must know the exact words that restore your funds. Treat online storage as hostile territory and do not type your seed into any website, app, or chat, because any connection to the internet can be compromised. Protect the device with a strong PIN and keep the PIN secret, and enable any optional passphrase only after you understand how it changes your recovery process. Verify receiving addresses on the secure display of your hardware wallet before you send funds, because the computer or phone can be manipulated and a wrong address can silently steal your payment. If a software wallet is involved, send a small test amount first and confirm receipt on a separate device so you can be sure the whole path works. Beware of blind signing where a compromised host hides transaction details; always confirm transaction amounts and destinations on the isolated screen of your hardware wallet before approving. Train yourself against social engineering by assuming every unsolicited request for seed words is malicious, and never reveal recovery words even to someone claiming to be support. Plan for physical threats such as theft or coercion by diversifying custody or using multi-signature arrangements when you hold significant value. Practice a recovery drill in a safe environment so you know you can restore your wallet, and when you update firmware use only the official update method while confirming device prompts on the hardware display. Keep records of where backups are stored and who can access them, and review your threat model from time to time as your holdings and life situation change. Self-custody gives you sovereignty, and with steady habits and clear rules you can protect that sovereignty while you help shape a greener, fairer future for crypto.
