The whole discussion in the article about 2FA resets is useless.
Blockchain.com wallet clearly states that every user should save their seed (24 worda) in a piece of paper to properly back up your wallet.
Saving passwords, 2fa, etc this is all pretty much useless, and the seed is all that someone needs in order to spend your funds.
What is terrible with this history is that someone stolen his funds. The author even suggests blockchain. Com employees.... I wouldn't say it is impossible...
I believe if fund are withdraw from the wallet then the key and security have been compromised, let say if the site does not give any right as to recovery keys that means the security of the wallet rely on the user.
