Apple has confirmed that iOS, OS X, and its “key Web services” aren’t susceptible to the now-infamous Heartbleed security flaw known to have affected countless popular websites.

The Cupertino, Calif. company made the announcement in a statement handed to Re/code. “Apple takes security very seriously. IOS and OS X never incorporated the vulnerable software and key Web-based services were not affected,” an Apple spokesperson said.

Google, Yahoo, Facebook, and IFTTT, on the other hand, haven’t been so fortunate.

Heartbleed is the codename given to a security flaw discovered in OpenSSL – software that’s used to encrypt online user information. More than two-thirds of all Web services across the Internet use OpenSSL, and as such hundreds of thousands of websites could be affected by Heartbleed.

If you’d been concerned that Apple’s mobile, desktop, and Web software could also be affected, fret not. For a list of vulnerable and previously-vulnerable websites, this CNET article could be of use.

For those of you who are concerned about password security on iOS and OS X, we’d recommend you consider taking 1Password for a spin.
