It depends on how you sign in. If you use Google or Apple, just sign in again with that account on your new device; there's nothing separate to recover. If you use an email passkey and you've lost it, say you got a new phone or cleared your keychain, you can restore login access through the email address on your account. Moneda sends a one-time code to that email; you enter it to prove the address is yours, then create a fresh login passkey on your current device and sign in with it from then on. Keep in mind this is separate from recovering your wallet. Logging back in gets you into the app, while recovery emails and Recovery Contacts restore your ability to sign transactions and move your funds. If you've also lost access to your account email, use those wallet-recovery methods instead.
