What is the difference between recovering my login and recovering my transaction passkey?

Moneda uses two passkeys, and they are recovered differently.

Your login passkey gets you into the app. If you lose it, you can recover access by entering your email and confirming a one-time code, then registering a new login passkey. This is quick.

Your transaction passkey approves payments and moves funds. Recovering it uses your recovery email and a security delay, because it controls your money. You create a new passkey, send a pre-formatted email from your recovery email address, and access is restored after the safety delay ends.

This is why getting back into the app does not always mean you can send funds straight away.
