if I created a wallet with a password and then exported the private key .Does in any way I will need the password or is the private key sufficient ?
Thanks
What is the wallet you use? because it might be different for some wallets.
For example, in Metamask, if you export the private key, it came in a raw and in unencrypted manner. So you don't need anything else but the private key. You can directly import the private key to a wallet from an exported Metamask private key.
