Tip #1: Keep all important information protected through encryption. Good encryption prevents the bad guys from reading data even if they get access to it. Good encryption means at least 128 bit key and preferably 256 bit key encryption, with each file protected by a strong password.
Tip #2: Don’t bank in public. Most of us now use the Internet in some fashion respecting our banking. Some of us use it more than others. You can use the Internet to access your bank accounts, check on deposits, make deposits, transfer funds between accounts, pay bills, and more. That makes for a very convenient situation because you can avoid going to a bank and waiting in line for Snail the teller. We have no issue with you doing those things (we do them ourselves); BUT, do not access your bank accounts on a public computer or a public network. If you feel you have no other option but to use a public network, make sure you have a VPN (virtual private network) for protection. To ensure that you do, set up access to one immediately, so that it will be in place when you need it.
Tip #3: Protect access to your financial accounts. Set up strong password access on each of your computers and mobile devices and also for each of your financial accounts. Change your passwords regularly (every three or four months should suffice). Remember a strong password includes a minimum of eight alpha/numeric/symbolic characters using both upper and lower case letters. Treat the passwords with care and secure them.
Tip #4: Do not use the same password for multiple accounts. Use a unique password and login name for each of your financial accounts. That way, if someone gets their hands on one account, they do not have access to the others.
Tip #5: Do not allow auto access to your financial accounts. DO NOT set up your devices to automatically access your financial accounts or to save your passwords and login names. Yes, we know it is a pain in the posterior to have to type that information yourself; but it will prove FAR LESS painful than trying to clean up the mess that occurs if someone steals your information and accesses your accounts.
