When accessing a DEX, your wallet app will prompt you to sign a cryptographic message. It confirms ownership using your unique keys in the background, so no seed or password is needed for each login

Cool, but I do need a password for the wallet app, right? Is the app a browser extension, btw?

A local password or biometric check may secure the app on your device, but it's just for unlocking your interface. Transaction approvals are separate, and yes—many multi-sig wallets come as browser extensions

Nice, thanks again. Might have to look into those at some point. 👍
