In a blog post, 1Password says that "suspicious activity" was detected in one of its employee-facing Okta systems. This suspicious activity was the result of an Okta data breach. Thankfully, 1Password claims that it "has found no compromise of user data or other sensitive systems, either employee-facing or user-facing," meaning that customers' passwords are safe.
