The private key is enough every created wallet is associated with a private key there's no mention of a password, the password is just a security feature added by the wallet developer and the password can be changed anytime if you're using a metamask and you transfer to another computer you can set up another password but you cannot change your private key that is associated to your address.

Thank you. That's what I understood from the beginning.
What I didn't understand is why people here are talking about saving the password for double guarantee.why not just save the private key twice ? 7 times..who cares ? I really don't see the usage of the password.
Thanks
