There seems to be a lot accounts setup at blockchain.com and blockchain.info with the passwords lost.

What happens with the bitcoin after a few years, does their support siphon the coins?

I mean they have the wallet IDs and wallet backups in JSON format together with email addresses, but if a person loses the mail associated with the wallet then BOOM, your coins are gone. A friend of mine has been trying to recover a long lost password since 2013, a big chunk of coins, but since his mail provider went out of business he has no way to request a backup wallet.

Anyone in similar position?

Can you even request a wallet backup via mail? I'm fairly sure that you aren't able to do that.

Blockchain.com insists that they don't have any role in keeping private keys, so if they were to be sending out wallet backup files via mail, wouldn't that be essentially holding private keys for the user? That's quite self contradictory imo.

Anyways, afaik support will not take your case and the only hope your friend has will likely be brute-forcing or somehow using existing clues to try and guess the password. At least he has the wallet-id.

Yes, you can do this in two steps.

1) go to login https://login.blockchain.com/#/reminder
there you type in the e-mail that registered the wallet.

2) you can request backup json file

With your "ideas" you can extract the hash with john and then brute force with hashcat.

Works like a charm
