If you're technical enough to encrypt your drives, you are technical enough not to use the same passwords on everything. I couldn't tell you any of my password

If you're technical enough to encrypt your drives, you are technical enough not to use the same passwords on everything. I couldn't tell you any of my passwords off the top of my head. They're all stored in password managers. Additionally, as someone else pointed out, it could be the case that the password he has expired and is no longer valid.
