Yet another security breach of a well-known online service. If you are still using weak passwords — and even worse re-use, them for different sites — then you need to change things sooner rather than later. Dan Goodin’s excellent article “Why passwords have never been weaker—and crackers have never been stronger” says it all. It’s a must read for every internet user.
Personally I’m a happy user of 1Password, which I can highly recommend. There are surely many other solutions out there, probably some for free. It doesn’t matter what you use, but for your own sake start using a password manager. Start today.
