Textual passwords are more commonly used in day to day life. They tend to be more vulnerable as far as security is concerned. Users tend to pick short password that are easy to remember which makes the password vulnerable for attackers to break. Furthermore, textual password is vulnerable to hidden camera, shoulder-surfing, key loggers, spyware and brute force attack. Graphical password schemes have been proposed as a possible alternative to text-based scheme. However, they are mostly vulnerable to shoulder surfing and key loggers.
