Comet will only ask for your wallet password when you're unlocking a wallet, not during switching from one wallet to another. The initial unlocking of Comet is a basic protective measure to ensure no one can immediately view your balances if they access your device.
While wallet addresses themselves aren't encrypted since they're considered non-sensitive, any action that involves the private key, such as sending tokens or signing a transaction, will prompt you to enter the specific wallet's password. This ensures your tokens and transactions remain secure at all times.
