What is a BIP-39 seed phrase?

A BIP-39 seed phrase is a human-readable list of 12 to 24 words that encodes the master secret used to generate and restore a crypto wallet. The standard maps these words to a fixed dictionary, so the phrase can recreate every private key in the wallet on any compatible device. For example, writing down your 12-word phrase lets you recover your funds if your hardware is lost or damaged. Because the phrase represents full control of the wallet, it should be stored offline and never shared.
