Prerequisites: The Ubuntu22.04 Server setup and familiarity with the 3-page Flask website setup. Found here: Flask 3pg Site
The full tutorial is found at PalletProjects.com Site. Our purpose is provide a slightly easier working setup and a summarized process on how that was done as to compliment the tutorial and provide insights to the workings of Flask.
With great thanks to the website Freecodecamp.org page on Setup user-authentication in Flask. The code, slightly outdated with some minor corrections, is integrated into a 3-page website with the aim of demonstrating the qualities of Flask-Login to make for an institutional website with private pages where the administrator has full control over the management of users.
Demo#3 - Flask Security App
Again great thanks to another coder called 'Keneth M', where the basis of the setup started with code found here. Using this as a foundation, a fuller application has been developped based on a database (Sqlite3 but easy to re-configure if one wishes to use PostgreSQL) and with Flask-Mail behind a contact page (assuming a tandemn iRedmail setup). All-in-all, it offers a good starting point for an institutional website with the robust Flask-Security providing email confirmation to new registrations prior to login.
