Completely blanked on my Blockchain password

[Egrodo]

I recently had to get a new HDD so I transferred my only Bitcoin to Blockchain so I can get it off later. Although, coming back to it now, I have absolutely blanked on the password for it. I understand that they don't reset passwords, but this is really confusing me. All my passwords are variants of a single base depending on what I'm using the password for, so naturally I used my 20 character financial password to first log in. This didn't work, so I ended up going through all my passwords that I have ever used for anything. None of them worked. I am sure I have the correct ID, and I have taken many precautions to secure this account. I have multiple backups of the wallet, but naturally they're encrypted too, so I don't know what I can do. I've looked into brute forcing the password using things like this: https://bitcointalk.org/index.php?topic=170694.0 and this: https://bitcointalk.org/index.php?topic=170694.0 , and I will resort to those as a last step. What do, BTalk? I can provide every possible form of verification on the account, but it really sucks to lose the only Bitcoin you have. Especially when you're 16 without a job and bought in at 110. I have that Blockchain account sync'd with Authy on a jailbroken iPhone, is there anything I could do there? I apologize for my newbieness on the subject, any help whatsoever would be so much appreciated.

have you tried restoring the back up to a local wallet "bitcoin-qt" trying your passwords on that

also make sure your keyboard layout is the same as before. if its a new install most defaults are US keyboard and if your UK the " and @ change places its can be a bitch at the best of times

It isn't that they don't reset passwords.  It's that they can't reset passwords. They don't have access to your current password. It isn't stored on their servers.  They have no way of knowing what it is.  What they have is an encrypted copy of your wallet (just like the backups you have).  To change the password, they would have to first decrypt the wallet with the password that you don't have, and then re-encrypt it with the new password.  Obviously if they don't have the current password and you don't have the current password, then this isn't possible.

All my passwords are variants of a single base depending on what I'm using the password for, so naturally I used my 20 character financial password to first log in. This didn't work, so I ended up going through all my passwords that I have ever used for anything. None of them worked.

Assuming that you actually used a variant of your "single base" I can think of a couple of possibilities.

It's possible that you simply used a variant that you haven't thought of yet.  If you continue to think about it, and try additional variants, you might come up with the right password.  It might also be possible to write a program that tries all possible variations of your single base

It's also possible that you made a typo when initially entering your password.  You can try various possible common typos and see if any of them result in the correct password.  It might also be possible to write a program that tries all possible typos on all possible variations of your single base.

Depending on how complex your password is, such programs may be able to find the password in a few hours, or it may take years.  If your password is really complex with a lot of likely variations, it might not be possible to find it at all.

I'm not familiar with Authy.  If it stores a copy of your password, then I suppose there might be a possibility there.

Hope you figure this somehow.  When I enter passwords checked it many times. I close and open it again to check if password work I before I send btc's on it.
