Why professionals choose Passcovery
Technology inside
Password recovery speed comes down to code quality. All core Passcovery algorithms are written in assembly and hand-optimized for GPU pipelines. This is not a wrapper over OpenCL or off-the-shelf libraries, but a proprietary implementation of SHA-1, SHA-512, AES, and RC4. The speed difference compared to typical solutions can reach orders of magnitude.
Our range of specialized products offers solutions from Excel to TrueCrypt. Each one is available for free download so you can test it on your own file and see the speed before purchasing.

Customer Feedback
“Impressive piece of software!”
Mats K., Sweden – about Accent ZIP Password Recovery
“Thank you, thank you, thank you. I stupidly password protected a document without keeping a copy that wasn't protected and no one in the family could remember the password. Passcovery broke the password for me - this document represented endless hours of work by my daughter in law and me. Thank you so much.”
Madeleine Sann – about Accent WORD Password Recovery
“Found my forgotten password quickly using a Geforce GTX650 GPU and clever combinations of attacks of AccentZPR.”
Andrew Mayne, United Kingdom – about Accent ZIP Password Recovery
