Raw seed is a hexadecimal number derived from the mnemonic phrase. It can also be called a private key. Most of the wallets in the ecosystem provide a mnemonic phrase instead of a raw seed. To restore your account from the raw seed, use Cere Explorer, the web wallet version. The Polkadot{.js} browser extension does not support this feature.

Like the mnemonic phrase, your raw seed gives full access to the account to anyone who knows it. It is not password-protected.

• Save your raw seed in a temporary text document and print it using a non-public printer.
• We recommend having several copies of the printed raw seed in separate locations and protecting them from physical damage.
• Make sure to permanently delete the text document with your raw seed after you print it.
• Do not store your raw seed online or on any electronic device.
• When restoring your account with the raw seed, double-check it after entering it to avoid any mistakes or typos.
• We recommend having a secondary backup option.
