Now at blockchain.info wallet I did backup my pass phrase. But I have no idea what my private key(s) are. There is no export that I can find. I understand there used to be.

enter image description here

If blockchain.info goes out of business, can I use my pass phrase to gain access to my funds from another wallet?

  • Can you clarify the part where you say there's no export option? (Screenshot, ideally) Aug 6, 2016 at 7:05
  • @WizardOfOzzie, done. personal info cut out. There is no export functionality any more in blockchain.info

The answer is yes, I can access my funds using only my pass phrase.

Mycelium, for example, when installed, comes up and asks if I want to restore a wallet from a 12-word passphrase, which is what blockchain.info created.

It then found my funds and will allow me to send / receive.

I have since learned that the pass phrase is just used to generate the private key using the SHA-256 hash algorithm.

  • The passphrase is actually used as the salt in hmac-sha512 (BIP39) Aug 12, 2016 at 0:43
  • @WizardOfOzzie, I'll research that and correct my answer. Thanks!
