Printing out an online bank statement is just as safe other banking services offered online provided some precautions are in place. Security measures help to prevent any fraudulent activity on an account.
An online account should have a strong password that cannot be easily guessed. A secure password should have at least eight characters combining both numbers, letters and symbols. Users should log out of the account immediately after using it. Security-enabled websites that start with "https" provide extra security for personal information such as passwords.
Users should not respond to emails that claim to be from their bank and ask for account details. Other security measures include calling the bank in case of suspicious activity on an account and avoiding sharing too much personal information on social sites.
