Any password manager should be able to “type in” the password. Or be a browser plugin that doesn’t rely on copy pasting, but use other mechanisms to inject it directly into the field.

There’s also mods in satisfactory. For example “satisfactory plus” is essentially a full rework, increasing complexity by 2-3x. Obviously needs to be updated for 1.0 first though… Just in case you need something until factorio dlc at the end of October.
Edit: if you’re familiar with factorio mods, it’s similar to and inspired by bobs+angels.
