If the data has not been filled in it cannot "leak".
Once the box with consent to the processing of your personal data has been checked, and the information filled in and sent, you have practically no influence on their future fate, except for the possibility to withdraw the consent. However, this is not a quick procedure, and it is quite difficult to monitor its fulfilment.
Therefore, when you agree to the processing of your personal data, be careful about what information you provide.
To make it easier, it is worth considering user passwords or full account details breaches separately. If the leaked data is outdated or incomplete, then the potential threat is lower.
Also, if you use two-factor authentication, a single password is not enough to gain access to your account.
Change Your Email, Account and Phone Number
Of course, changing your email, account and phone number isn't something you want to do on a regular basis, but you can have a separate virtual phone number, card and mailbox for online reference - they'll be easier to give up if needed and none of your friends or colleagues are going to use them to contact you.
Preventing data breaches is an important task that requires awareness and security measures. We've looked at some basic measures you can take to prevent personal data breaches. It is important to remember that everyone should be responsible for the security of their data and take appropriate measures to protect it.
