Implement robust hashing algorithms (like Argon2 or bcrypt) for user passwords, and use secure secrets management systems (such as HashiCorp Vault or AWS Secrets Manager) to handle API keys and application passwords. 5.

No password protection. No security. Just a plain text file with millions of sensitive pieces of data. This data included usernames, passwords, emails, and URLs for a host of applications and websites, including Google, Microsoft, Apple, Facebook, Instagram, and Snapchat.
