Has the company been involved in any security incidents that have potentially compromised user data? If so, it's best to look elsewhere. And while you're researching password managers, it's important to consider the company behind the service. Independent security audits can also help bolster trust in a password manager. Look for a password manager that operates on a zero-knowledge basis and secures user vaults with industry-standard AES 256-bit encryption. You're putting a ton of trust in your password manager to keep your logins safe, so the security of the service should be your top concern. Here are the most important things to consider when choosing a password manager: Security CNET has thoroughly tested dozens of password managers over the years, and we've developed a pretty good idea of the types of things to look for in a quality service. With the numerous password manager options available, it can be overwhelming to choose the right one.
