Abstract: The system and network security is strengthened by passwords, which is a significant part of an Authentication process. Most commonly an Authentication method using either alpha-numeric password or Graphical password, which has crucial drawbacks like dictionary attacks and shoulder-surfing. The Grid based Graphical Text password Authentication have been emerged as an alternative solutions to overcome the potential vulnerabilities due to conventional schemes. Additionally, originating the “Grid Systemization and Text Enlargement Technique” for classifying a preferred theme Image. By clicking the grid on that theme Image it enlarges a next sequence of password. This method depends on “Image-Image-Alphanumeric password” and the successive mien relies on prior option. This scheme has been acquiring prominence, because of its integrity and security as well as the Grid Systemization and Text Enlargement Technique.
