Some netizens say that having a mnemonic is enough, and you don't need to remember the password. This is true for general mobile wallets, but it doesn't apply to certain software wallets and most hardware wallets.
Because when using the BIP39 standard to generate a seed from a mnemonic, these wallets require a password to generate the correct address. Without a password, you cannot obtain the correct address. Examples include KuCoin, Bitcoin Blade Wallet, Trezor's private wallet, and SafeWallet's password-protected wallets.
This method increases security; even if you leak your mnemonic, it's okay as long as the password is complex enough. It would be difficult for hackers to brute-force the password from the mnemonic. However, if you forget the password, recovery becomes very difficult.
