Seed Phrase Security Best Practices

Why the seed phrase is the actual key

A seed phrase is a sequence of words that can recreate a wallet's private keys and full access to its funds. Anyone who obtains it can access those funds — it functions as the real, ultimate key, regardless of any password protecting the wallet app itself.

Keep it offline, always

A seed phrase should never be typed into a computer, stored in a text file, emailed, photographed, or stored in cloud storage. Any digital copy creates a real opportunity for it to be stolen remotely.

A durable physical backup

• Write it on paper, or use a more durable medium designed to survive fire or water damage.
• Store the backup somewhere secure and, ideally, separate from the device it protects.
• Consider a second backup location for redundancy, kept equally secure.

Never share it, under any circumstance

Plan for the unexpected

Consider how a trusted person could access funds if something happened to you, balanced carefully against the risk of exposing the seed phrase to more people than necessary. This is a real, practical trade-off worth thinking through in advance.

What to remember

• A seed phrase can recreate full wallet access — treat it as the real key to your funds.
• Never store it digitally in any form, including photos or cloud storage.
• Keep a durable, secure, offline physical backup.
• Never share it with anyone, regardless of how the request is framed.
