Problem
Due to the quarantine due to the Covid-19 pandemic, thousands of teachers had to perform their duties from home, to which the "Pablo Neruda Polytechnic High School" was no exception. This institution has a staff of 30 teachers from various specialties and a management team of 5 teachers. Because all the work is done from home, the school had to find a way for both teachers and administrators to have access to the necessary information: electronic class book and general student information system (SIGE), ministerial platform in where all the data of the students of the school are entered. The school's IT manager, a teacher who completed a diploma in educational computing, installed the application of both systems on the personal computers of the workers and gave them a general password, which must be changed after logging in.
