Password management software OneLogin said Wednesday it had "detected unauthorized access to OneLogin data in our US data region." It said it was investigating the incident and had taken action to halt the intrusion.

ZDNet reported that the company told users, "all customers served by our US data center are affected and customer data was potentially compromised."

Key context: This isn't the first time a password manager has faced a hack. Popular tool LastPass was hacked in 2015. And OneLogin faced a different hack of one aspect of its service last year.
