When we register on social networks, email services, or online banking websites, account protection often comes down to just a password. However, most users still rely on simple combinations that attackers can crack within seconds. Ukrainian cybersecurity experts repeatedly note that in mass password leaks, the same primitive keys appear again and again — such as “123456,” “qwerty,” or “password.” Most of these passwords are guessed by automated hacking tools in less than a second. To reduce risks, it’s important to know which combinations to avoid, how to create strong unique access keys, and why it’s safer to enter data only on websites with encrypted connections.
