For a new crypto person, it is very easy to use the Blockchain wallet but for advanced level users, this wallet is not as secure as it advertised on social media. The 2FA adds more secure account access but bypassing the 2FA sending email and applying the received instructions from the support team will be enough. As mentioned before, the simple mechanism is good for new traders and I have used this wallet for a long time. There is no choice to extract the private keys from a wallet and you should take the seed for finding the private keys of your personal BTC address.
