If you have forgotten your password, the best way to recover access to your Kukai wallet is to use the seed words that were generated when you first set up the wallet. The seed words are a series of 12-24 words that are used to generate your private key, which is then used to encrypt the keystore file. It is important to keep your seed words safe and secure, as anyone with access to them will be able to access your Kukai wallet. To recover your wallet, you can simply import your seed words into the Kukai wallet and gain access to your wallet again. It is always important to remember your password and to keep your seed words safe, as this is the only way to access your wallet if you forget your password.
