One problem I had when using a similar technique is how to change passwords. Some services require regular password changes, security breaches require it, etc.

So I needed some additional piece of information, namely how many times I've had to change passwords, so a new function argument.

Eventually I gave up and started using a password manager.

That's what 'n' is for in the code above. There are only a small handful of sensitive websites I use that require frequent password changes and I usually sync them all to the same incremented value of n every few months.

Gotcha. I think that the manual effort of that was what put me off managing passwords myself.
