Installation
************

Installing Flask-Security-Too using:

   pip install flask-security-too

will install the basic package along with its required dependencies:

* Flask

* Flask-Login

* Flask-Principal

* Flask-WTF

* email-validator

* itsdangerous

* passlib

* Blinker

These are not sufficient for a complete application - other packages
are required based on features desired, password hash algorithms,
storage backend, etc. Flask-Security-Too has additional distribution
'extras' that can reduce the hassle of figuring out all the required
packages. You can install these using the standard pip syntax:

   pip install flask-security-too[extra1,extra2, ...]

Supported extras are:

* "babel" - Translation services. It will install babel and Flask-
  Babel.

* "fsqla" - Use flask-sqlalchemy and sqlalchemy as your storage
  interface.

* "common" - Install Flask-Mail, and bcrypt (the default password
  hash).

* "mfa" - Install packages used for multi-factor (two-factor and
  unified signin): cryptography, pyqrcode, phonenumberslite (note that
  for SMS you still need to pick an SMS provider and install
  appropriate packages).

Your application will also need a database backend:

* Sqlite is supported out of the box.

* For PostgreSQL install psycopg2.

* For MySQL install pymysql.

* For MongoDB install Flask-Mongoengine.

For additional details on configuring your database engine connector -
refer to sqlalchemy_engine
