clear text password to ?

Right now I am using a clear text password. I keep it in mySQL RDS on AWS in a table. I was planning on moving it to use fusionAuth to maintain passwords but I am out of time (and energy) to get that into the code (and fusionAuth is changing their pricing strategy). So I am back to using regular old CI3 code for the time being.

What is the best practice to secure that password and keep it in my mysql table? I have a way for a user to self register and also to reset their password already in the code. 

I use this script (https://www.openwall.com/phpass) to hash the password and store it in the database. At login, for example, the password sent is also hashed and compared to the passwords already stored.
