Cheats are fine until they quietly disable something you cared about, which is why the consequences matter.
Short answer
Anything built into the game is safe; anything needing an external program is not, and online use is a ban either way.
If a site asks you to sign in to receive a code, it is not a code. Anything that requires downloading a program is not a cheat code. The useful part of any answer is the part that tells you what to do differently.
Achievements and save files
A code that softlocks a mission is a known risk in more than one of these games. Enabling cheats disables achievements in most games, and the warning is easy to miss. If this seems to describe a different version, it probably does, and that is the thing to check first. Achievement locking is usually per-save rather than per-account, but not always.
Codes typically do not persist through a reload, which surprises people who use them for convenience. Consensus and correctness overlap less than the upvote count suggests. Codes are usually case-insensitive but rarely space-insensitive.
What each one actually does
Single-player cheats are a supported feature; the same behaviour online is a ban. Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. Glitches get patched and codes tend not to, which makes codes the more durable option.
- Make a separate save before enabling anything.
- Ignore any code that requires signing in somewhere.
- Stop and reassess if two attempts fail in the same way.
- Save manually before using anything irreversible.
- Enter codes exactly, including spacing.
- Treat any number without a date attached as approximate.
Anything promising online effects
Console entry uses button sequences with tight timing, and mistiming reads as a broken code. Everything below is framed around the current state of Minecraft rather than a launch-week impression. Case and spacing matter more than the lists suggest. Controller-entered codes need rhythm rather than speed.
Patch notes move numbers around constantly; the shape of the answer holds even when a specific value shifts. Anything that alters save state can corrupt it, which is why a separate save is worth the ten seconds. Anything requiring an external program is a different category with different risks attached.
What you give up
Screenshots age faster than text, which is why this describes rather than shows. Codes entered correctly and rejected usually mean the wrong platform variant. Some effects cannot be undone within a save, and the game does not always warn you first.
What follows assumes you are on a current install and have not modified it. Some effects stack in ways the developers did not intend and the game does not handle gracefully. A cheat menu built into the game cannot get you banned, whatever the forum says.
When a code will not take
Where the game contradicts its own documentation, the game wins. A code that worked on an older patch may have been removed rather than changed. Console commands and cheat codes are different systems with different consequences.
Where people go wrong
- Downloading a helper tool for something the game already does in its own menu.
- Assuming a guide from an older season still describes the current version.
- Following console instructions on PC, or the reverse, and blaming the method.
- Giving up after one attempt that failed for an unrelated reason.
Minecraft FAQ
Do the effects save?
Rarely. Most reset when you reload, which makes them convenience rather than permanent change.
Will using these get me banned?
Not in single-player, where they are an intended feature. Anything claiming to do the same online will absolutely get an account banned.
Is this specific to one platform?
The reasoning is not. Anything that genuinely differs by platform is called out where it comes up.
Is there a faster way to do this?
Usually, and it usually trades reliability for speed. Which one you want depends on whether you plan to repeat it.
Bookmark it if you like, but honestly, once you have done it once you will not need to come back.
