I am one of the members of the Tezos XTZ Recovery group. I along with a few others have had a good success rate with helping people recover their passwords. Many of the people we talk with were unaware that it was necessary to keep their password. For many of them thought that the PDF was all that they needed. The “Private Key” was there and they had seed words to recover from.
The good news is that most people are very bad at creating secure passwords. We help people setup the tools and guide them to recover their own password. If you need assistance, we are here to help.
Here is a guide I wrote for Windows Users and for Mac Users. You can also check out a tool I wrote to make it easier for Windows users, along with other tools on my GitHub page. We also have several commits to John the Ripper to make the Tezos ICO password cracking process easier and better.
I will never ask you for your seed words or other private information. By keeping that information secure and by running the tools on an offline computer, the password recovery process is safe and secure.
