A seed phrase is a list of recovery words used by many crypto wallets. It can recreate the private keys needed to access your cryptocurrency.
Why seed phrases are powerful
If your phone, computer, or hardware wallet is lost, the seed phrase can restore the wallet. That also means anyone else with the phrase may be able to take the funds.
How to protect a seed phrase
Do not send a seed phrase by email, store it in cloud notes, paste it into websites, or share it with support accounts. Real wallet support should not need your seed phrase.
Write it down carefully and keep it somewhere safe. For larger amounts, consider offline backups, hardware wallets, and separate storage locations.
