Long gone are the days when a strong password was enough to secure your account. It is now easier (and more difficult at the same time) than ever for attackers to gain access to your private data such as email addresses, passwords etc. The only way forward is to use measures such as two-step verification which require the use of and physical 2SV security keys, like Google’s Titan Security Key.
