Just like an account where one's fiat currencies are kept so also is wallet where digital assets or cryptocurrencies of crypto lovers are kept. Can the wallet be vulnerable to hacking and if possible how can that happen? If you have experienced it before, I want to learn from your experience.
No system is safe. As long as it is online, it can be hacked. There are a lot of phishing site where hackers can gain access to your personal info by creating a website. Also there are links that can install malware on your computer. Just make sure that your computer is malware free, and the website you are accessing it legit. You are responsible for your own security.
Although they (hackers) use phishing sites to steal all the assets you have but they will not be able to access your wallet if you use 2FA, especially you use the google authenticator. The pattern of the Google Authenticator is an impossible way for a hacker to access your wallet, because every minute the password changes constantly unless the hackers have access to your smartphone.
