When your password leaked, it can put your email, social media, banking apps, and business accounts at risk. The first step is to change the affected password immediately and avoid using the same password on other platforms. You should also enable two-factor authentication to add an extra layer of security. If the account is linked to sensitive information, review recent login activity and remove unknown devices. For better protection, use a strong, unique password for every account and consider using a trusted password manager. Acting quickly can help reduce the chances of account misuse, identity theft, or financial loss.
