With all the phone apps available now to allow you to move money conveniently between friends and family, it is important to remember to protect your phone in case it is lost. Once you have loaded those apps on your phone, without good password protection anyone who picks up your phone can spend your money! Sure you can probably get most of the money back, but in the meantime your normal payments might be returned unpaid plus you lose access to your funds until the mess gets staightened out.
Make sure you have enabled passwords on both your phone AND any financial apps. Keep your phone updated with the most current software. Consider adding biometrics like fingerprints or facial recognition.
