Recently I have created a simple password generator tool that helped me a lot since it is not storing or intercepting anything at all.
It is not a password generated by big tech giants and it is totally unstored by any db.
And also I wanted it to be small and as fast as possible.
Please take a look to https://repasswordgenerator.com . It is totaly free to use and I am planning to create a simple tool app in a couple or days.
