So, keeping our personal and financial data as secure as possible. In the following, some guidelines learn to keep our private personal and financial data safe online.
1. Choose your PIN wisely.

A combination of uppercase and lowercase letters, numbers, and symbols will offer us more security.
2. Secure network. If we have a wireless network at home or workplace, make sure that it is secure. A hacker can gain access to anything you do over an unsecured network in a matter of seconds.

It may take a little more organization to use different passwords for each site, but it can help marginalize the effects of unauthorized access to your accounts.
4. Don’t put private information on public computers. If we’re away from home, make sure not to save private information onto a computer used by the public. If we’re accessing a private account at the library or cyber café, make sure to log out completely from our accounts, and never choose to save login information (like username or password) on these computer.
5. Protect computer’s security. Use as many tools as you can to guard our computer information from the nefarious. Failing to protect our computer is just as bad as leaving your door unlocked, your windows wide open, and a sign on the mat, saying, “Burglars, come on in.”
