Replying to this pretentious comment for the sake of others reading this:
Run history | grep genpasswd for why this is not a good password storage solution. One must image skill issue.
If you think the CLI is the cool kid way to go, use https://www.passwordstore.org/, but tbh I don’t recommend that either.
This is not true at all. https://en.wikipedia.org/wiki/Post-quantum_cryptography good place to start if you’re genuinely interested. Most password managers that are worth while will be using symmetric cryptography which just requires longer key lengths to survive in the quantum age. AES256 should be fine for the foreseeable future.
