More than 1800 one million concurrent mark. Even so, Mojang wants everyone to know that this is not a tip-of-the-iceberg situation—It hasn't actually been hacked—and also to remind its many players to be careful about how they handle their s.
Mojang's Owen Hill explained in a recent blog post that the s were compromised not by hackers, but as the result of phishing scams by unnamed "bad people." All compromised s have been reset, and Mojang has sent out emails to everyone affected—and if you didn't receive such an email, then there's nothing to worry about.
"No-one has gained access to the Mojang mainframe," Hill wrote. "Even if they did, we store your s in a super encrypted format. Honestly, you don’t need to panic."
Hill also urged players to never provide their information to non-Mojang sites, and to use different s on different sites to minimize the potential damage of actual security breaches. And if, after all that, you're still a little nervous about the whole thing and want to change your anyway—"You sound like a sensible one," Hill wrote—you may do so here.
