A #Bitcoin private key can be stored as a mnemonic phrase in two ways.
1. With a single point of failure:
Seed Words only (either 12, 15, 18, 21, or 24 words)
or
2. With NO single point of failure:
Seed Words + Passphrase (up to 100 characters long)
NB. Multiple copies of both seed words and passphrases (stored in separate locations) are necessary to prevent catastrophic failure from loss or theft.
