Password Generator built using React, Material UI and with e2e tests

What challenges did you encounter, and how did you overcome them?

At first my slider allowed length of 1 to 20 and I was struggling on the behavior when the slider is at 1 and when a user checks more than 1 checkbox. I solved this issue by eliminating that possibility by making the minimum value of my slider to 4.

What specific areas of your project would you like help with?

I need help with my solution since I'm not 100% sure if it's secure enough when generating the password. My hooks would need some review: src/hooks/useGeneratePassword.ts.

Also on the side I'm trying to learn Docker so if you would review my Dockerfile and docker-compose.yml I would appreciate it a ton.
