The old version of Blockchain's recovery mnemonic can be recovered here:
login.blockchain.com/wallet/forgot-passwordIf it accepted the old mnemonic, you'll be presented with your wallet ID and password.
But I highly doubt that the 4-words mnemonic will be valid, but it's still worth the try.
Tried but gave checksum invalid. I am not sure if possible to create a wallet.aes.json file with her info and then import here:
https://login.blockchain.com/wallet/import-walletThat means that the 4-word mnemonic backup is invalid, as expected.
For the "
wallet.aes.json" file, you'll have to download it from their server using "
download-blockchain-wallet.py" script from btcrecover but it also requires email authorization since they wont just provide something sensitive without verification.
AFAIK, they provide that file to users in the old version after creating a wallet, try to search if she still has a backup/email of it.
You'll also see the contents of the 'wallet.aes.json' file if you put your wallet ID in this URL:
https://blockchain.info/wallet/00000000-0000-0000-0000-000000000000?format=json (
replace 0's with your Wallet ID)
But then again, it will only work with accounts without a linked email address or it will show something else if the session (
IP & browser) isn't verified yet with your email.
Anyways, they have issues with authorization email most of the time.
Try their support if they can verify that you have the correct email address and it's just their system that cannot send the email.

So which one is it?
The second one. Only problem is that when she entered the email address in the login page, she didn't get any verification email, so she probably changed the linked email account in her blockchain.info settings but doesn't remember.
That's still good news, since you have the password.
The '2FA code' only comes after that 'email authorization' if she enabled it.
