Seed Phrase Security: Mistakes You Should Never Make

A recovery phrase is one of the most sensitive pieces of information in crypto custody. If an attacker gets it, a device password is not enough to protect the wallet.

Keep it offline

Do not store a seed phrase in cloud notes, email, chats or screenshots. Digital copies can be exposed through malware or compromised accounts.

Never give it to support

Legitimate services should not ask for your seed phrase to unlock funds or restore an account. Treat such requests as a strong fraud signal.

Build a recovery plan

Keep a physical backup in a secure location and think through what would happen if the backup media were damaged or lost.

Slow down before signing

Verify the domain, network, destination address and transaction request before approving. Many scams exploit urgency rather than technical weaknesses.

FAQ

Can I write my seed phrase on paper?

It is a common backup method if the physical copy is protected from unauthorized access and environmental damage.

What if I shared my seed phrase?

Treat the wallet as compromised and consider moving assets to a newly created wallet after carefully verifying the situation.
