Normally, when logging into an online account, you will only enter your account name and password to be able to log in, but this is also quite risky in case your computer is installed with keylog or other components. Tracking software to steal passwords, especially when you use the public internet, will be easily infiltrated by hackers. For example, if you log into primexbt, binance, huobi exchanges, they often ask you to use 2fa because if you use each password, when your computer is hacked, your password will be taken from you like bitcoin, ethereum and usd. Yours will be stolen by crooks.

This means that even if a hacker can steal your account and password, it will not be able to log in.
