Idk I run my own PO3 server on Java and everything but the launcher is fine. I’m sure Bedrock is completely molested though.
If you run your own server it’s as simple as setting
Online-Mode: false
And installing an account management plugin if you open it to other players (so people can’t just easily change names and impersonate someone)
I exclusively played on and ran cracked servers for 6 years (2011-2017), shit rules
