Strong Password Generator

A password that never needs to be typed by hand or remembered has no reason to compromise on length at all — the only real cost of a longer, more complex password is the human inconvenience of typing or recalling it, and a password manager removes both of those costs entirely by storing and autofilling the value. Twenty-four characters drawing from the full character set — uppercase, lowercase, digits and symbols — produces roughly 150 bits of entropy, an amount so far beyond any brute-force attack's reach that it approaches the practical ceiling of what "more secure" can even mean for a single account credential.

This preset is the right default specifically for anything stored in a password manager and never typed manually — most online accounts, in practice, for anyone who has adopted one — where there is no reason to trade any strength away for memorability, since memorability was never going to be needed.

Excluding visually ambiguous characters like `0`/`O` and `1`/`l`/`I` exists as an option specifically for passwords a person might need to read off a printout or type manually — for a password that only ever gets copied and pasted directly from a manager, that ambiguity never actually gets encountered by human eyes, so there is nothing to gain from excluding those characters and a small amount of entropy to lose by doing so. This preset leaves the full character set enabled for exactly that reason: maximum strength, on the assumption the value is being copied programmatically rather than transcribed by hand.
