Another nudge which we've added to the site is the different tiers of course completion accomplishments. If you complete a class within 2 weeks of starting it you'll get Gold (12.5k points), 4 weeks Silver (6250), 12 weeks Bronze (3125), and > 12 weeks Plain (1250).

We know it's a common behavior to treat the site like Netflix and to add stuff that you just think you may get around to someday. But the fix is easy, just unenroll from the classes you're not going to take any time soon.

OpenSecurityTraining2 @opensectraining.bsky.social · 15/06/2026

Upgraded server news 3: New password complexity requirements - 18 characters, no complexity requirements, since 26^18 >> 62^8 (hopefully we don't need to educate you on password best practices ;)). This doesn't apply retroactively, just to new registrations or password resets.

OpenSecurityTraining2 @opensectraining.bsky.social · 15/06/2026

Upgraded server news 1: OAuth registration & sign-in via GitHub or Google. Let us know what other providers would be useful as they're now easy to add.
