Here is another useful post nc50lc on this topic (Wallet.aes.json)
That's only useful if he has access to the encrypted wallet file.
Without access to the email to authenticate the login, he wont be able to get it using tools that can download it from their server.
So I have the following info:
Password
"Unfortunately, we are unable to help recover or reset passwords, nor can we change back the email address of that account. This is not a matter of policy; this is due to the very way the file encryption is designed. If you’ve forgotten your password, please try every possible password combination you may have used when you created your wallet, bearing in mind punctuation and capitalization."
What's troubling in Osiris100's case is the fixation of Blockchain's support in the password (
unable to reset password) despite him having access to the password.
Perhaps they are misunderstanding your query that leads them to deny any request to reset your associated email address?
As far as what the so called "
very way the file encryption is designed" is concerned, the email address isn't involved in that encryption as the "
wallet.aes.json" file in their server can exclusively be decrypted by the password (
plus second password if set).
