Buy Fortnite V-Bucks on mmoga?

I once have a question unzwar I've been thinking about mmoga v bucks to buy because they are cheaper than ingame but now I ask myself the question if that is really safe because I have to give my account password.Nachdem I have made the purchase can I just change my password again but still I'm a bit unsure because my account is very valuable.

Yeah, I also got some VBucks and I'm very happy too

Once you make the purchase, someone logs in and earns the V-Bucks, so you would actually have to enter a time period when the person can come online.

You can change your password after the period. That the account is stolen is possible, but unlikely because these people want to earn money. If they bring something, they will get rid of the job.

I also want to buy V-Bucks, but I also do not know if that's really safe?
