The mnemonic is a 12 or 24 word phrase that lets you recover account access if you lose your PGP key, password, or 2FA setup. The platform shows it once at enrollment; if you lose it, you lose the account. Write it on paper. Two copies. Two physical locations. Do not photograph it. Do not paste it into a password manager. Do not type it into a notes app. Paper, full stop.
Why paper: every other storage medium is shared with other applications and exposes the mnemonic to vector classes (clipboard scrapers, cloud-sync leaks, photo gallery upload services) that paper does not have. The mnemonic is the recovery floor of the entire account; treat it as the highest-value item to protect.
