When to Use?
If you keep personal data online, there's a chance it's ended up on the dark web. Hackers and identity thieves use data from the Dark Web to launch phishing schemes and cyberattacks in an effort to gain access to your sensitive information. These breaches allow hackers to access your information, which they then try to sell on the dark web.
1Password Business accounts give users access to the Watchtower tool, which alerts users about compromised websites, weak passwords, and password reuse. They utilize the website Have I been Pwned, which is regularly updated when hackers post user information that has been compromised on the dark web.
Procedure
Your 1Password account has this functionality activated by default; you can learn more about it on their knowledge page.
