How is it possible to recover a wallet password when the wallet words are provided before you even enter the password?


Restore password

If you forget your wallet password, then you can restore your password from your wallet words.

  • @WizardOfOzzie This is a different question! One questions asks how to restore a wallet from a random file location, and this question asks how it is possible to recover a password from a wallet using only wallet words when the password is given after the wallet words are generated. How can your reading comprehension be so dismal? – Chloe Aug 4 '15 at 19:44

    @Chloe Please assume good faith on behalf of other users, and don't call them names. See bitcoin.stackexchange.com/help/be-nice, rules 1 and 2. There is a good-faith interpretation of Wizard of Ozzie's comment, which is that he disagrees with you about how similar the two questions are. – Nick ODell Aug 4 '15 at 23:39
  • @Chloe Settle down, it says possible duplicate. My reading comprehension was based on two very similar threads created very close in time to each other. I didn't shut the thread; just wanted clarification, which you've now given – Wizard Of Ozzie Aug 5 '15 at 3:45

There is a copy of the password stored encrypted with an AES key derived from the wallet words.

Thus if you forget your password and still have a copy of your wallet you can use your wallet words to recover your password.

  • So the password is stored twice? Once encrypted with wallet words, and another time hashed for normal use? Then how can you change your password? Does that mean the wallet words are also stored unencrypted in your wallet? – Chloe Aug 4 '15 at 19:48
  • If you change the password some backups are updated to reflect the change as well. See multibit.org/en/help/hd0.1/change-password.html for details. – Gary Rowe Aug 19 '15 at 17:45
