#2. Only Use Strong Passwords for All Devices
If you did not think that using a strong password for your mobile device was important before, you definitely should reconsider that now. This is especially the case since you will be using your mobile device to process and finalize credit and debit card transactions for your customers.
Think about the massive amount of confidential data that will be saved and captured within your payment solution as well as the internal storage of your actual device.
If your device is not secured with a strong password, the average cybercriminal would not need to work very hard to gain unauthorized access to it. According to Microsoft, your password should:
• be at least eight characters in length
• not contain an actual word
• not include your real name
• include a combination of letters, numbers, and special characters.
