Use commas, multiple single quotes, and semicolons in odd non repeating patterns to really screw with parsing, be sure it also contains emojis if allowed, Unicode characters and write out Unicode such as the space (   )

All that along with the typical password security measures should fuck with exports, parsing and escaping just enough to get a malicious actor to at least toss your entry out.

You've done it right if you break the db and can't log in yourself lol.
