My friend recommended the Badlion client and he looks really good (the client) but I'm a little scared because he doesn't officially come from mojang but you have to enter your account details…
… Do I have to pay attention to something or can I be hacked or something? Or is it safe and can I enter my account details?
Have been using it for a while and it didn't happen to me
Is safe. I've had it for min. 1/2 year and had no problems.
Youtubers would not advertise that if it were illegal
Yes, it's safe to use since he's been out.
The company behind it is ESL Gaming or Turtle Entertainment
