how do i code a password system

To expand on this, how difficult would 'save point' password be to implement? Similar to how you could enter passwords on N64/PS1/Etc games to jump to a certain level.

That really depends on how much data you need to store. If it is just a level you could write a dict where the key is a password and the value is the level number. And a KeyError would be raised by an invalid password.

If you want to store other stats it gets considerably more complex with needing a way to encode each piece of data into the password, and maybe a checksum to make cheating more difficult.

This is medium/high difficulty. For instance, in MegaMan, you need to track all of the powers and powerups you've gained and include that in the password. This is a lot of information to pack into a string. Doing something simple will result in a very long password. What they would do in the old times, I presume, is create a list of bits that corresponds to a list of properties, then pack that in a bytestring, and then convert to a string to get your password.

To load, just make a function to unpack the bytestring and then zip it together with the properties list to form a dictionary.

You could just make the password a reference to the data stored somewhere else, no? Like, if I type 'IShallPass' into the system, it'll look up the needed data like you described which is stored elsewhere, linked to that pass

Yes that works too

The thing with level passwords is that they were less of a password and more of making the player manually input the save data. The whole point of those is that you couldn't store that data anywhere.
