Mobile Banking Apps use the device’s secure storage to host sensitive data.

Mobile Banking Apps use out-of-bank multifactor authentication to validate users at login.

Password Security

A password represents a shared secret between the end user and the system they are authenticating. The system cannot differentiate the real user from another user who also knows the password. For this reason, it is essential that users keep their password private.

A well-chosen password has two important characteristics; it should be easy to remember, and hard to guess – a password that has to be written down is not strong, no matter how many principles of a good password are applied. Users should be advised not to write down the password anywhere. This is an example of a more secure password: Mpis4y2!

  • At least 8 characters in length
  • At least one numeric digit
  • Use of upper and lower case
  • Use of special characters
  • Not a word in the dictionary
  • Not easily guessed
  • Can be easily remembered as an acronym: My password is secure 4 you 2! Adding another character increases the time required to crack the password almost 100 times.
    • This is an example of a less secure password: Password1
  • Is based on a word in the dictionary, Password1 is among the top 630 most used passwords and can be cracked instantly using a dictionary attack.
