YOUR RECOVERY CODE
Write this down. It is the account. It was generated in your browser and never leaves it — we derive your signing key from it and see only the public half. Lose it (and any passkeys) and no one, including us, can recover the account.
CONFIRM IT
ADD A PASSKEY?
A passkey lets you sign in with a tap, with the key held in your device's secure hardware. Platform passkeys may sync through your Apple or Google account (end-to-end encrypted); a hardware security key stays on the key. Either way the recovery code remains the root.
YOUR ACCOUNT NUMBER
Balance: credits (beta grant). Sign in any time with your passkey, or with the number + recovery code.
