Passwords: how to respond to leaks and where to check for compromises?

Prompt response to credential leaks and regular checks for compromise help prevent financial losses and the takeover of important accounts. Remember that timely software updates and creating backups have a much higher priority than fine-tuning the interface or secondary features.

To check the security of your data, use specialized and proven services such as Have I Been Pwned, which aggregate leaked password databases from open sources and the dark web. Regularly enter your email addresses into the search bar of such platforms to find out in time if your accounts were involved in recent security incidents.

Set up automated breach notifications and enable two-factor authentication on all critical resources, including email, banking, and work tools. If your address or password is found in a leaked database, immediately change your credentials on that site and on all related resources where the same combination was used.

Build a reliable habit of periodically changing passwords for key services and using unique combinations for each individual site. Automate the backup process for critical databases to minimize the consequences of potential hacker attacks or hardware failures.
