Hi I'm doing initial research on changing the way joomla authenticates a user. I want to do this only for the frontend user and not the admin user.
WHY I want to do this? I'm importing a list of users from a different CMS which uses SHA2SALT and SHA1 hashing technique. I have to rewrite that system so that it uses joomla and the old users can utilize the existing passwords to login. I can make a feature where the have to change their password immediately after the first login on the new system.
I'm exploring my options of getting this done and I want to know the best way to achieve this. viz. whether I need to write code or if there are any 3rd party plugins to achieve this.
Would this be the best way to go ? https://docs.joomla.org/J3.x:Creating_an_Authentication_Plugin_for_Joomla
