In short
A seed phrase is the wallet. Anyone who knows it can move the funds. Keep it offline on something physical, and never type it into any service or reveal it to anyone.
Key points
- Whoever knows the phrase controls the wallet
- Never store it in phone photos, cloud notes or an email draft
- Paper burns, soaks and fades — consider a durable medium such as a metal plate
- Multiple copies in separate places protect against loss but widen the exposure surface
Definition
A sequence of roughly 12 to 24 words from which a wallet's private keys can be regenerated. Also called a recovery phrase or mnemonic.
A seed phrase is not a password. A password can be reset; a seed phrase has no reissue mechanism. Conversely, those words alone grant access to the same funds from any wallet app. Lose it and it is gone; leak it and it is taken. That asymmetry is what makes handling it awkward.
Start with what not to do. Do not photograph it on a phone (photos sync to the cloud). Do not type it into a notes app or password manager (one broken account then loses everything). Do not email it to yourself or paste it into a chat. The moment it touches anything online, treat it as a phrase that will eventually leak.
Practical storage starts with writing it by hand on paper. Paper is vulnerable to fire, water and fading, so for a long-term holding it is worth considering a durable medium such as a stamped metal plate. Store it somewhere no one else sees and you will not forget — people really do lock a phrase in a safe and then forget the safe's code.
Whether to keep several copies is a trade-off between loss and leakage: one copy can be destroyed by a single disaster, while more copies raise the odds of discovery. Splitting a phrase across locations only works if you can reproduce the recovery procedure exactly — a scheme so elaborate that you cannot recover from it has the same outcome as theft. Under none of these schemes is there ever a reason to type the phrase into a website or app.
Watch out for
- · Any site, app or person asking you to enter a seed phrase is a scam, without exception
- · If a phrase has ever been stored online, create a new wallet and move the assets
- · If you entrust it to family for inheritance purposes, do so only with someone you trust completely
Frequently asked questions
Does a hardware wallet remove the need to store a seed phrase?
No. A hardware wallet still generates a seed phrase at setup, and that phrase is the only thing that restores your funds if the device breaks or is lost. It needs the same care.
