I invest in Waves during ICO. I don't understand how I do it but I lost my password and my seed phrase. I use application for chrome on windows and I have access to the login page. I know my adress. I found on windows a txt file with Checksum and Cipher. Is-it possible to find password with this data ? Thanks
It's not possible to recreate a file from a checksum - if that is what you are asking. No password or seed - no access.
Always backup you seed people, we can't repeat this enough.
