Subject: recovering online account passwords
. I don’t know if this happens to many people but through my research I found this approach. and tried to utilize it and realize that it was built for different purposes than I was using it for. I would still love to know how to use the software and to get online and give it all the correct information and let it go.Thank you so much for putting me on your list. I really love the idea of password recovery and this type of operation to tell you the truth I never had much luck with it. It was over my head technologically, and when I was on the drive in the cloud they were charging me per Minute or kilobyte or whatever and I didn’t want to pay the charge for that search without knowing exactly what I was paying for. Your emails have enlighten me slightly more than I was but I’m not a programmer and I’m not a network administrator and so I am also not a criminal so I wasn’t trying to break other peoples passwords. I just did something and Google locked me out. Microsoft locked me out. Everybody locked me out and I wanted to find my old passwords . I don’t know if this happens to many people but through my research I found John the Ripper and tried to utilize it, and realize that it was built for different purposes and I was using it for. I would still love to know how to use the software and to get online and give it all the correct info and let it run. The run times also seemed extremely long. It’s probably because I was using it on only one machine and did not have enough computing power for it to run faster. Sometimes it would say I would have to wait 18 to 24 hours for the results. So I have not been using it. I ended up erasing everything on my computer and starting over again and lost much valuable data. They know it could’ve been saved. I just did not know how to do it.
Thank you thank you again
