Your key
Fromensics makes an Ed25519 key in this browser. It can’t be exported, it’s never synced, and it’s never sent to us. Each browser profile has its own key. Your contacts confirm it once by comparing your four words, found in Settings → Signing: “When a contact calls to check it’s you, read them these.”
Your promise
Turn on Bank details change only when signed to add a promise under your footer. Contacts who trust you are warned when an unsigned email asks them to change where money goes.
